Now I'm really confused. It may be a different model. Anyone else know for sure? I'd be the first to admit it if I was wrong. Check out this link (scroll down):Hey Frank, I believe what you're looking at in that video is just a different year. I think both are correct.
So if that's correct (which I believe it is) the diecast in NOT a 1951 !I think I know what's going on now....the taller tail fins with the small in-set taillights are 1951 and EARLY 1952 year models. (Like the one in the video you posted.)
Cars made later on starting mid-year in 1952 until production ceaced in '54, had the fins with the taillights built in like your model above.
