Technically I only got the head of the Machine. After asking some family my grandmother apparently got the machine from a family friend who had it converted to run with a speedmaster motor and light and made a table for it. I don't know why they would not have just used the original cabinet if it had been a treadle, maybe for space?
It does not have a spoked wheel but rather what I was a retrofitted wheel to match the motor.
I looked up the serial number in the I
nternational Sewing Machine Collectors' Society and that says its a model 15 from Nov 3rd 1920 whether it was a treadle or hand crank is not mentioned.
I tried using this: http://needlebar.org/main/15chart/index.html to compare the model 15s but I really don't know enough about the bobbin section for that to be of any real use.
Thank you so much for all your replies!
I uploaded photos of the bobbin area if anyone is willing and knows about that sort of thing. Thank you all again!
