Brass Head

I expect to receive one of these machines - a somewhat battered hand-cranker - in the next couple of days. It may or may not arrive with a working shuttle/bobbin. Will my spare Singer 127 shuttle/bobbin work or will I have to find a proprietary Jones part? (If there's a genuine Jones bobbin with the machine, I'll do everything I can to get that restored, but I do want to get the thing working at some point by some means.

Thanks.
