I recently inherited my grandmother's old Singer. She is in need of a good clean up and a new belt, but I'll bet she'll run like a deer! Anyway, the bobbin, or bobbin shuttle case is quite unusual (at least to me) The serial number looks like "G6642870" although it is quite faint. When I looked online, it looks like it was made in 1919 in Elizabeth, New Jersey. But the bobbin case has me a bit stymied. I have seen older Singers with a regular bobbin and bobbin case - one a 1904 model. (unless the owner was mistaken about the age) I am wondering if this bobbin shuttle is specific to a particular year. It has the Egyptian designs on it that I have seen on a lot of old treadles. Thank you for looking!
