I never really kept count of what I have in the collection overall. Across 1985-88, I listed all the variations I had in the collection for the Lone-Star, Lledo, Corgi, Dinky and Matchbox Rolls-Royce model variations, listed in pocket books and I used to carry these to toy fairs so I could check models agains the entries to check for new variations. It got to the stage these books were becoming too cumbersome to carry so had to re-learn all the variations and keep them in my Head!
I still have those books and I see in one of them I have actually written some totals dated October 1994, 724 models listed across all these Red books, 8 books in total!
So no, I do not now know how many models overall I have, but there's always room for one more...
