had to take these off a banjo I recently acquired on eBay as they aren't working any more and may have been made between mid 1920 to mid 1940's, I am only selling because someone may be able restore these or use the rare triangular buttons etc, please note, these are not usable in the state they are on , and the black on them is paint, so originally they were metallic, probably cheap plated etc, please also not, I pay for postage and always use royal mail, who pick up from my house, please don't reach out to eBay about postage, it's all sorted this end, thanks.
