Thanks Rich! I need to look at a few to see what I want and then I'll contact.
There were so many drawings in each MM magazine, and in different scales, that I can't recall which were 1/4". I do recall a lot of 3/16" and of course HO.
Hundman did a good job of covering the Seaboard Air Line and Atlantic Coast Line, so those I'll be searching for. Plus the N&W "J" and many others. About the only engines I've never cared for are the Camelbacks and (as he hides behind a brick wall) the GG1s.
Not just engines, there are plenty of caboose and rolling stock drawings that draw my attention too.
