I am in the process of digitizing a lot of paper files of model railroading articles and stuff I've collected over the years (and throwing out about 60% as stale techniques or of no further use to my interests).
I ran across this catalog sheet for Cape Line trucks. These were formerly made by Red Ball, and I believe the line was later retooled in plastic by Eastern Car Works (correct me if I'm wrong about the latter).
This might be worth keeping just as a guide to identifying some rather obscure trucks. It is certainly not complete by any means, but there are some here I've never seen anywhere else.
I miss Cliff Line and Central Valley trucks. Not as good as some we have now, but really nice for their time and heavy too since they were diecast metal.
