Singer 15-91

This is a nice Singer model 15-91 electric that my father gave me from his collection. The 15-91 machines have what is often called a "potted motor". The motor is housed on the upper back of the machine and connects directly to the gears, eliminating the need for a belt. This makes for a very strong machine. The stitches this one sews are very nice, as can be seen below. I plan on using this machine for quilting.

Below are some sample stitches from this machine:

This machine came with a very nice bentwood case from the correct time period. 

I have placed the machine in a Singer cabinet that I had, shown below.

Below is a photo of something I decided to test the 15-91 with. It is two Weave-It squares, with some spool-knitted tubes in the middle as a batting. The 15-91 sewed right through all this wool without a ball-tipped needle, and without a problem.
