I have 12 axles with brass wheels that I bought on ebay. There are 8 loose, and 4 in a bag.
I had no idea how small they were until I opened the package! Here they are compared to a USA or Aristo wheel:
I’m sure that somebody here can use these. I thought they might be Narrow Guage, but you can see they fit on “normal” (45mm?) track. Could someone identify these?
I paid $64 plus shipping. Will sell for same.
