List of Singer models by shank type? How about bobbin type?
Do you know of one somewhere on the web? These seem like they would be very useful for collectors, especially newbies. I read a comment on the vintage sm subreddit where they mentioned that decision on whether to get one machine or the other could be decided by matching the bobbin type to one you already have. Kind of a genius idea.*
Anyway, if there isn't one, maybe we can do one in a Google doc or something that can be shared for editing and pin it or file it or whatever.
*Or ludicrous, especially around here where my herd of 20ish is a comparative baby, lol. Also, I have a Featherweight, a 301, a 401a, and a Necchi Supernova, so bobbin-wise it's already too late for me. And shank-wise as well.
