Billy here are the pictures. This machine is in great shape. The number is 3171412 -- I sent a picture, but hard to read with my camera -- I couldn't get a clear picture.
The bobbin winder is just kinda stuck on the back -- not sure how to work it -- it must attach to the main belt?
The tension disk is on the front on the machine towards the top. The front of the machine has decals instead of a face plate. I have no idea how to thread this machine.
The bobbin is very narrow and just slides over a little handle into the bobbin case -- the bobbin does not have a removable case.
Very interesting!
