Very common industrial sewing machine. Lots of info on the net and parts available. Some models are walking foot but 31-15 (most common) is not. I understand some use for Quilting with large harp, though I don't have one. $70 sounds about right if motor, clutch, and machine seem OK. This is like the Model 15 of Industrials.
