I'd like to add a few things to my Bachmann On30 Shay. Who makes steam detail parts in O scale? (Or for that matter, even diesel stuff!) I can think of Grandt Line. There's also Precision Scale. I know there are others. But no names come into mind this morning. Anyone have some additional possibilities? Boxcab E50
Contact Coronado Scale Models, they'll know more than just about anyone else. They seem to have all sorts of odds and ends. Caboose Hobbies would be my second choice. Check out The Backshop...they are a manufacturer.
I think Ozsteam also has some really nice stuff for Shays and Climax. Don't forget your junk box for chain and wire that can be used for hose
