Thanks for all your help with this; I obviously know zilch about Standard Gauge, so your information is greatly appreciated.
1. Wow; it's older than I would have imagined.
2. Yes, on both counts.
3. The motor itself is, I think, pretty quiet. There is a "chattering" which I think is due to the axle holes in the frame sides being slightly worn and a little enlarged.
I have ordered some replacement motor brushes; will changing these simply be a question of removing the screws that hold the caps (and wires) in place?
Thanks again. 👍

You bet. Supposed to be fairly easy but never is. Caps are interference fit, but getting them off without the tube moving can sometimes be challenging. Screw just hold wires on. Be gentle... the brass is thin wall and a little fragile.
