When I got to the shop I told him what I found out about the machine and I wasn't interested if it had plastic gears but I would have to take the top off to check. The guy at the shop let me bring it home yesterday the 237 and it looks like all metal except the bobbin casement. It needs a lot of cleaning and a spool pin and a o ring but other than that it seem okay. He's come down to 10.oo what do you think no extras 1 foot, manual. What do you think?
