Motor on a 12...shudder.... Ewwwww.
The 12's are some of the best and smoothest sewing machines you will ever use. There is a reason that they were copied even more than the later model 15's. Every major country in the later 1800's through the early 1900's copied it.
The needles are actually still being made (5000 at a time, special order - but folks sell them)
Replacement bobbins are also still available.
They take standard low shank feet so the options are almost limitless.
Get a handcrank version and you will never go back to an electric portable!
