Having exhausted my HO freight car trucks with metal wheels, I now have a need to purchase replacement wheel sets.
Trucks in my spares box requiring metal axles and wheels are as follows:
C&BT Shops equivalent to Walthers 1001/1012
Intermountain pre-war A3
I realise that the situation is more difficult with the demise of Reboxx but any suggestions of a source for both code 88 and 110 wheels would be greatly appreciated.
