These new additions to my shuttle collection arrived in today's mail. It shows the front of them and the backs of the ones that are different. Hubby bought them for me from Ebay. There was also a metal 'Boye' shuttle that has pat applied for on it. Does that mean that it is older than the ones that say pat approved 4-17-1923? Does anyone know? There was also a detach a spool shuttle that looks like the ends were soldered. Were they all soldered or was this one altered by someone?
