I got a few sets of old athearn trucks in a box of parts at the last show. I have a few questions as to when they were produced and how they fit into the evolutionary ladder.
First, I have seen Two versions of the Hi-F truck. Which was first?
I have seen photos of a gear drive with a metal case for the early GP9.
Are these trucks in the photo the first snap together trucks introduced in 1962? When were they discontinued?
