OK, I know that my lotus was built in July of 1973, "73073862R" But I don't know if it is a late 1973 or early 1974 model. Or is the no difference? It seems that the dealer told it was a 1974 Model. Any idea when the change takes place? I know that American Cars are sold in the next calendar year starting in September of the previous year. So the manufacture must be earlier than that. Do the Brits do a similar thing?

As mentioned, Lotus were not always titled in a consistent manner, and the idea of distinct model years is very loosely applied. I think this is common among cars of limited production from small manufacturers.
For what it's worth, my car is 3682R and also built in July 1973, just slightly before yours. It is titled as a '74 (it was sold new in January 1974), but I have taken to referring to it as a '73. There are a few distinct features that differ from Europas referred to as a '74 vs a '73, such as the engine cover lift-cylinders and the map pocket on the wall between the seats, and my car does not have them. There are a couple other differences as well, but these are the ones I use as easily spotted key identifiers. I'm not sure when these features first appeared, or if they appeared all together as a model-year upgrade, but I guess it would have been sometime in late summer/fall 1973. As far as I know, all differences between a "1973" and a "1974" model year are relatively minor convenience items, and that the general spec of the car did not change.
