Thank you, mea for getting back to us with information from the Singer technician.

I'm curious as to why this is. If so where would you like it to be? Some day I need to fashion one as the top front one is broken off of my 237.

I've heard a lot about new bobbins not quite right for vintage machines. I know they now have 15 and 15J plastic bobbins. I was kind of surprised to see that according to http://www.singersewinginfo.co.uk/bobbins/ that the 237 takes plastic 15 bobbins. It does not say which 15 plastic bobbin. According a parts file I have the bobbins are 81348 for the 237M23. When I put that number in search I got https://www.sewingpartsonline.com/bo...0pk-81348.aspx which says it is guaranteed to fit, along with 237, the 15-30. That would seem to indicate that it is the flat top and bottom bobbins, not the ones that seem to be a little domed or thinned edges.

Welcome, Kissamew. Thank you, too, for the information from singersewinginfo.

I was curious about that and was wondering if it might be that the drop feed knob had been broken off. Then I looked at the manuals I have for the 237. Some of them, I don't seem to be able to find a date. Those without the date have the drop feed knob on the bed of the machine. However, I have one that is dated 1967 shows a machine without the drop feed and used a feed cover plate for Free Motion Work.

I also noticed another difference between the 1967 manual and the later ones. The bobbin tension was in a different place. On the early one it was in the middle of the arm, whereas, the later one was above the thread guide above the tension assembly.
