Thanks to all for your suggestions. I'm at work, so I don't have any promos in front of me . To clarify, the early AMT promos used nail heads from 1948 or 1949 to probably 1952, slotted screws in 1953 and 1955, nails in 1954, and slotted screws from 1956 onward (disclaimer: don't quote me on all of those years as I'm going from my memory). I think all of my Jo-Han promos have the nail head or non-slotted screws. Some of the promos have the nails in so tight that there is no way to get a pair of pliers on the nail head, and a putty knife or chisel is too thick to pry up with. Is there some other effective tool to pry these up without damaging the head or gouging the chassis?
I have a few windows to reglue, as well as a few chassis to straighten out from kids leaning too hard on the models when playing with them.
I could also use a couple of screws for a '56 Roadmaster 4-door hardtop. These are smaller than the screws used on the AMT models of the 60s.
Thanks,
Jim
