theres an old hardware store here in kc called harry j epsteins(google for their website and catalog)
was talking to steve, one of the two brothers who own the place(harry was their grandpa), about farriers rasps just wed.
he told me he just bought a crate of new old stock(made in usa) nickelson farriers rasps and they would be in next week sometime.
he said they would be selling them for about $15.
good place to check in with periodically. they often get in cases of new old stock hand tools(and weird old military surplus items).
steve is always on the lookout for old warehouse finds.
the good ones made in usa. i have picked up numerous nickelson and other wood rasps, files and such.
great guys to deal with. they back up what they sell.
ifn yr ever in kc it is well worth yr time to stop in. there is no place else quite like epsteins.
