It is designed for a 16D.
Not at home this weekend (somewhere in the middle of France for a 6 hour race of vintage 1/32 kit cars, on a newly refurbished and expanded track with a 50+ foot straight!), but will try to weigh mine and post some pics.
Mine was maybe my luckiest purchase ever - there's a small shop on our residential street specializing in old Dinky toys; he occasionally gets a slot in one of his lots and I've always told him he could ask me for info. A few years ago, he called to me as I was passing and said: "What is this?" It was the brass Lotus in its blister card, dirty but unassembled, and no box. I brought over my AW catalogs and told him about the car. I also said when you're ready to sell, let me know, I'm interested!
A few weeks later, I passed by and stopped in, asking why I hadn't heard from him: "Oh, since I hadn't heard from you I put it on my website." Gulp... "is it sold?". "Non". "So, how much do you want for it?" "80 euros" "Ok, think I'll take it Monsieur... ".
Next year, the Bordo vintage race is for "open wheelers"... Do I dare?
