I only saw some prints of the actual car available on ebay. Different decals, everything in the kit but the body is chromed (even the little Jim Clark figure), different exahust type--this is what I can see from the photos available on ebay. I'd like to see some engine pictures though. I suppose this is what I meant by reference. This is an old Testors kit. I've seen the AMT kit on sale on ebay for a chunk of $. This one I found at a garage sale.
