Lovely miniature! I am late to the party but these are just a few from my treasured miniature collection...
The patent number on the little white ones was registered by Imperial, so they're from Prov Do but not actually made by Prov cutlery.I have the little providence cutlery white one! Few of em laying around from an antique store that had a bunch...I was amazed they have half stops haha. I agree the quality appears no where near the original one you posted but the blade isn't that lazy which is pretty impressive.
Thanks! I have over 80 of the little buggers now, but that little scrimshawed one is my fave!
