Got a copy of Higby's list. 
Good place to start. You should get a copy. "The McCoy Story" book is too,except photos, but has little about production. Making a photo list of all McCoy items for myself but is slow because of the lack of photos available on the web to "borrow". 
So far I have over 100 pages (photos are big). Catalogs are a good place for an interested person to start also but they are hard to find. And, they're in B&W too.
All-in-all, McCoy is great. Tinplate came back from the dead in the 50's-60's thanks to the McCoys in my opinion. Reguardless of what the "chatter" is, as long as there is a McCoy to make trains, there will always be McCoy trains.
Long may they run.
