OK everybody after a lot of hard work and research I've just uploaded a heavily revised "Type Numbers" page: http://www.lolaheritage.co.uk/history/type.htm as well as updating the entries for the early Types.
I hope this is now a definitive list of all the Lola Types but I'm sure someone is going point out a mistake or two .
A note on the Year entry, I've arbitrarily made this the main year(s) the car raced. For some types the first few cars were often built in the closing months of the year but usually did not race until the following year. Additionally a few cars might have been built in the year after the model raced. So for example the T596 Sports 2000 had the first 3 cars built in December 1983 but the remaining cars were built in 1984 so it's shown as "1984" on the table. I hope that makes sense.
I shall now sit back and wait for your corrections.
Gerald.
