Default Singer 237's enormous bobbin/case! (and manual source)

I found a pdf manual for my 237's and on page 6, I was astonished at the apparent size of the bobbin case and bobbin. See below compared to the operator's hand. Very impressive!

Maybe it wasn't page 6, but the manual also tells you how to operate it in a treadle! These were late 60's and early 70's machines.

A 237 in a treadle would be an ideal off grid machine.

I would think that with a bobbin that large, as in the picture, you could sew for a few months before needing more bobbin thread.

Actually, there are more manuals for the 237 and one does not have the larger dial for the pressure regulating dial. I can't find a free one on the web but a paid version at https://manualsoncd.com/product/sing...uction-manual/. I got mine from Yahoo Groups. Here is another manual that does not have the treadle and the bobbin is not quite as large, but still larger than really is. https://www.manualslib.com/manual/29...?page=1#manual

I think this is probably the one that you got from ismacs https://www.manualslib.com/manual/86...?page=1#manual

Funny!

I do really like my Singer 237's.

They are almost fool-proof.

Digging around in my digital stash, I find I have the adjusters manual for the 237, too. Lots of stuff you hope you never need to know.

It's about 6 megs, if anyone wants it. pretty sure it's too big to attach.

The bobbin drawings are not to scale. According to the videos on Youtube, it uses the same bobbin as the 15-91.
