Welcome to the Quilting Board!
That the machine moves freely is a plus, and makes it a candidate for refurbishing, altho it would cost more to refurb than it would be worth on the resale market. Guess it all depends on what you want to do with it. I'm not sure what model it is...one of the "letter" models. (Model H, Model K, Model L for examples)
One day, you'll only be a memory for some people. Do your best to be a good one.
Getting back to posting pictures of my collection - here are the two 15's. Still have not located an older 15 treadle.
Here is the 15-90. So far, this is my favorite 15. 1945 vintage
And the 15-91, 1952 vintage
Cabinet needs some TLC - someone left an iron sitting on it for a bit too long. Not sure if I'll try to fix that or not- it's kind of neat . . .
Singer 101, 1922 vintage. The stitch length is the nob on the bed of the machine. Notice the pull chain for the light.
The underside - quite different than other Singers of this era
The controller is built into the machine, and the knee bar mounted in the cabinet pushes a rod into the machine to activate it.
And the potted motor on the back
This machine was considered high end and came with an extended set of attachments. I've acquired a hemstitcher with the appropriate plate also.
It came with the darning foot and feed cover. I don't think this would work for quilting though.
And the cabinet specifically designed to house this machine.
Singer 201 1948 vintage
This one has Pride of Place in my Queen Anne cabinet.
I love the drawers and compartments inside.

While DH oiled everything up well for testing, he did not put any oil in the reservoir. I see no evidence of any dripping on the dust cover for the cabinet, so it does not look like it ever dripped. Though that may only mean no one else ever added oil to the reservoir either.
This is DH's least favorite of my Singers - based on working on them, not using them.
