Hi Brian,
If you haven't already, you'll want to join NARCOA. You might also want to join the Railroad Motorcar Maintenance list at Yahoo Groups.
Harsco no longer has the Fairmont Birth Cards. They've been turned over to the local historical society there in Fairmont, MN. You can contact them for information.
If you don't already have a manual for the car, you'll want to find one as they are indispensable. If a narrow gauge manual proves impossible to find, then a standard gauge manual will have some good info. Try [

BTW, I own an S2. If you have any questions I'll do my best to answer them.
Welcome to the hobby,
