It is marked "Japan" on the underside of the loco, but no other marking I can see. I'm told by a friend who knows more about vintage brass than I do, that this is a Balboa/Katsumi model. Look at pictures an judge for yourself. I don't know much about vintage brass HO trains. I don't have an HO layout, but loco ran when I bench tested with a transformer and test leads.
Sounded "dry", has been in storage for many years. Should be cleaned and lubed before attempting to run on a layout. These are old and will often need tinkering and TLC. I only sell to the USA.
