However as the editors conducted their research it became apparent that the Chapman\u2019s design principles were adopted by many competitors in period. This started a train of thought. It became obvious that many of the iconic Chapman designs were emulated in period and since on a larger scale.<\/p>\n
Although this is considerable complement and indication of leadership it has consequences and the editors see merit in discussing these in the context mentioned.<\/p>\n
The quotation above is attributed to Charles Caleb Colton [1780-1832] during his life and career he was a cleric, writer and collector. Educated at Eton and Kings College, he travelled and lived for a while in the United States. Evidently a man of taste and refined aesthetic he settled in Paris where he is believed to have gambled and acquired paintings and related works of art.<\/p>\n

What is imitated?<\/strong><\/p>\nIn the field of design and many others the scope and extent of imitation is colossal. It embraces diverse subjects and objects including:-<\/p>\n
\n- Furniture to cars<\/li>\n
- Jewelry and particularly watches<\/li>\n
- Fine art and sculpture<\/li>\n
- Antiques and fashion<\/li>\n
- Food and architecture<\/li>\n
- Various branches of industrial design e.g. electronics and cameras etc.<\/li>\n
- Plagiarism in speeches and academia<\/li>\n<\/ul>\n
Why imitate with particular reference automobile<\/strong><\/p>\n\n- As we have noted imitation is often prompted by the desire to own or experience what is not generally available either through price or availability<\/li>\n
- Status<\/li>\n
- Aesthetics<\/li>\n
- Upgrading or improvement<\/li>\n
- User drivability<\/li>\n
- Protection of original [term used very advisably because of potential abuse.\/ excuse and alternative agenda]<\/li>\n
- Economic \/commercial advantage in various forms including elimination of design , trial and error and development through to sales based on successful pattern format, specification etc.; possibly there might be overtones of providing same specification at lower price<\/li>\n
- It ought be recognized that what seems like imitation can result from the application of scientific principles and of legislation or regulations<\/li>\n<\/ul>\n

Patents<\/strong><\/p>\nPatents have evolved as a form of protection against theft of ideas and unique design. The measures cannot be 100% totally successful but do have an important role to play.<\/p>\n
See A&R article \u201cPatently Obvious\u201d \u2013The Lotus 25 for an extended analysis of patents.<\/p>\n
Aesthetics and car body design are difficult to patent and control.<\/p>\n
Iconic Automobile Imitation<\/strong><\/p>\nImitation frequently occurs for those iconic vehicles not generally available. Or whose status is such people aspire ownership or possession to such an extent they are willing to copy. The most copied of vehicle marques\/ models are:-<\/p>\n
\n- A.C. and particularly the Cobra<\/li>\n
- Jaguar: C&D Types,SS and XKSS<\/li>\n
- Ferrari notably the 250 GTO<\/li>\n

A.Competitors in Period [Sports\/racing and Prototypes]<\/strong><\/p>\nThe Lotus 23 and 23B.<\/strong><\/p>\nHarvey:-<\/p>\n
\u201cMeanwhile Chapman had persued his Lotus 19 line of thought by developing his 1962 Formula Junior car the Lotus 22 into Lotus 23 sports racer .this was a smaller car than the Lotus 19 and used a variety of engines with the Ford 997cc, 1092cc and 1470cc units the most popular\u201d<\/p>\n
This was small displacement Sports racing car designed to meet FIA rules. It\u2019s thought that the car was projected to accept engines between 750- 1300cc.<\/p>\n
Twite remakes on the common acceptance that the 23B was \u201cbased very much on the Lotus 22 Formula Junior car the Lotus 23 used the Ford FJ engine which had been so successful in previous years\u201d<\/p>\n

1,558cc<\/td>\n | <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Brabham<\/strong><\/p>\nTwite observes:-<\/p>\n \u201cWith sports \/racing cars following closely to the design of single seaters it was no surprise when Jack Brabham followed up his successful Formula Junior and Formula I cars with a sports\/ racing model .From the point of view of sales it was unfortunate that the Lotus 23 had already established itself in both 1,100 cc and 1,600 cc form but even so Brabham has proved to be more than a match for the Lotus\u2026.\u201d<\/p>\n The Brabham ranked amongst the Cooper Monaco. It was conventionally designed. It conformed to Appendix \u201cC\u201d relating to dimensions and luggage capacity etc.<\/p>\n A variety of engines were fitted to the Brabham but significantly the twin-cam Lotus Ford developed by Cosworth proved successful with its 140-150 bhp from twin Weber carburetors. The alternative are the Ford Formula Junior [see A&R dedicated article], the Coventry Climax 1,100 and potentially an enlarged Climax engine car.\u201d<\/p>\n Elva Mk.7<\/strong><\/p>\nThe editors quote Twite at length as it\u2019s considered there is no better summary:-<\/p>\n \u201cFrank Nichols who runs Elva Cars previously manufactured a great variety of cars ranging from the Elva courier road sports car to the Elva formula Junior car but in 1961 he arranged for Trojan Ltd to take over production of the Courier model and later ceased production of the Formula Junior car as he had on many occasions expressed his dislike of this Formula. This allowed him to concentrate on sports \/racing cars and in 1962 he introduced the Mk.VI\u2026\u2026\u201d<\/p>\n This evolved and developed into the Mk.7 [see specification tabulation]. Twite informs us the chassis was space frame\/ multi-tubular weighing 68 lbs. complete with light alloy under tray and all brackets.<\/p>\n Again Twite notes:-<\/p>\n \u201cFrank Nichols is not particularly fond of highly modified production engines and he prefers to fit the FWA Coventry Climax 1,098 cc sohc engine for 1,100 cc racing \u2026\u2026.also available are the Cosworth-Ford 1,100 cc engine and the Lotus-Ford twin overhead camshaft unit\u2026\u2026\u201d<\/p>\n Subscribers are sure to be aware that Porsche and BMW engines were adopted in 1964.<\/p>\n Merlyn Mk.4A<\/strong><\/p>\nMerlyn started in Formula Junior [see A&R dedicated article].They too seem to have seen the opportunity to mutate the basic formula Junior concept and created an Appendix \u201cC\u201d sports racing car.<\/p>\n It follows the pattern of the other models listed incorporating a multi-tubular space frame. Like the Lotus 23B alternative fuel tanks can be accommodated and also like the 23 the bodywork is of glass fibre with the front and rear sections opening easily for accessibility.<\/p>\n Like the other cars listed a variety of engines are possible not least the 1,600 cc tohc Lotus-Ford. The Merlyn has performed well in club level racing.<\/p>\n B.Current Generation Lotus Imitators [special reference Lotus Seven]<\/strong><\/p>\nThere a few points to make with regard to Lotus [particularly Seven] inspired kits:-<\/p>\n \n- Chapman conceived the Seven as production car; essentially with conformity of specification but offered in kit form to avoid purchase tax. The kit was complete. It was rather like a complete car dismantled and offered back for assembly<\/li>\n
- Modern kits vary in the extent of professional completion .Some return to the Lotus Mk.VI idea that Chapman tried to avoid with the Seven<\/li>\n
- We try and avoid terminology but the words replica have different meanings and there are many kits that a Seven inspired .They may have a passing resemblance to the Seven .Into this debate enters the litigation to protect the Seven appearance<\/li>\n
- The kit industry has a history dating from the 1950\u2019s [and some before ;if specials included], this expanded through the 1960 [e.g. Mini Marcos].Into the 1970\u2019s the classic car industry was starting to take off and baby boomers possibly wanting something more individual sought a kit car option<\/li>\n
- Of the factors encouraging imitation of the Seven possibly most significant were:-<\/li>\n
- That it was constructed in a traditional front engine\/rear wheel drive layout<\/li>\n
- That Chapman had used mass production engines that were widely available like Austin and Ford, these remained available .Into the 1970\u2019s some cars might be 10 years old ,Mot failure but attractive as donor vechicle for kit. Slightly later the trend would continue with the Ford Sierra one of the last mass produced cars with front engine rear wheel drive<\/li>\n<\/ol>\n
The motives of the provider kit industry manufacturers <\/strong><\/p>\nThis is interesting considering as Caterham are probably preeminent in the field and continue the Lotus practice of comprehensive package. Caterham can also claim the technical and conceptual heritage of the original. There is excellent availability and second hand cars.<\/p>\n Despite this and Ortenburger records in detail the international list of Seven like kit manufacturers the motives might include :-<\/p>\n \n- Undercut Caterham<\/li>\n
- Offer more DIY option to reduce costs , increase participation , reduce overheads<\/li>\n
- Some manufacturers might be result of owner racers, offering a product they use in competition [owners in turn being in engineering or fabrication etc.]<\/li>\n
- Some might feel their product meets national regulation and donor vechcles<\/li>\n
- Some might feel a younger generation want a more updated specification ,performance and looks<\/li>\n
- New generation of owners , expectations budgets<\/li>\n
- There are racing classes for Seven like cars<\/li>\n
- The impact of testing and safety<\/li>\n
- The attraction and practicality of using reasonably ready donors for example Austin Healey Sprite for Westfield Eleven<\/li>\n
- Demand<\/li>\n<\/ul>\n
The motives of kit customers<\/strong><\/p>\nWe have touched on some of these above .A more complete list might include:-<\/p>\n \n- A desire for a second inexpensive car and the driving experience<\/li>\n
- Wanting a hands on craft experience\/pride of constructing own car<\/li>\n
- Seeking alternative to bland mass production offer<\/li>\n
- A desire to customize or personalize vechicle<\/li>\n
- Rites of passage considering reputation of Lotus [for some an alternative to performance motor cycle]<\/li>\n
- To use in track days ,hill climbs\/sprints or other competition events [i.e. 750 Motor Club]<\/li>\n
- The attraction of affordable, incremental build costs<\/li>\n
- The owner of suitable donor or easy access to [at time scrap yards, local press etc.]<\/li>\n
- Those seeking a borrowed imagery of iconic Seven [see production numbers \/against which survival rate and world distribution. Impacts on supply\/demand \/price]<\/li>\n
- Direct imitation of the original for various motives<\/li>\n<\/ul>\n
The Modern Kit car Industry<\/strong><\/p>\nAgain it\u2019s worth referring to Ortenburger. The kit car industry is international and significant.
