Well, not sure if you mean that the machines had to be from 1962 or before, so I will just list the top 3 from that year I would like to play, have played, or own.
1st: I have a 1962 Williams King Pin, and it would be brand new then and I am sure it was a hit especially if that diner was in or next to a bowling alley. (Best 4 flipper game IMHO)
2nd: Gottlieb Bank A Ball (Great Pool theme)
3rd: Toss up between a Williams Trade Winds or a Gottlieb Tropic Isle (both great getaway themes)
