Thanks, Cathy - here are some closer photos of the bobbin winder. I replaced the tire recently, and it works extremely well (well, as long as I keep the wheel moving forward...). I did another closer of the SN, and can you all tell if the first number is a 3 - or a 5? I wonder why it would be so chipped, unless someone tried to chop out the plate. Lots of curiosities, which is why this is such a fun pursuit.
I really appreciate all the comments, I honestly did try to read through as much of the previous threads as I could before posting my inquiry so's not to duplicate questions. You all are amazing!
