The big Supercar is a die cast (I broke the antenna off ).
My old man was a Methodist preacher. We moved at least every 5 years. If they built a new parsonage during our stay we'd move two more times at that same charge. I moved 11 times between 1951 and 1971. Everytime we moved the model collection got scrapped and I had to start over. Lost some pretty good stuff in those first two decades. The last move, I packed my own stuff and still have several of those. When I moved the last time in 1972 I swore the next move would be the cemetery.... I'm still here.I agree with the Monogram kits in the '60s - I think I built every one of them at least once!
John, You should take your OVER ABUNDANCE of kits and open a hobby store...either online OR brick 'n mortar.
