Their stock can very but you might try Landwerlen Leather in Indianapolis. 1-317-636-8300. They don't really have a website. I love going to the store, it's like stepping back in time. Very friendly and very helpful.
Not sure if there is a Husqvarna group on Facebook, but there are old sewing machine groups. Many different domestic ones and some have files about refurbishment. There are also some old forums on other platforms.
It looks like a domestic treadle It looks to be in very good shape. If you need a straight stitching domestic that won't have problems with a motor, that one looks nice and the price seems good. The table looks to be in good shape also..
