Antique Singer 31-15 lockstitch single needle industrial treadle machine. Needs a little work to be the perfect off-grid sewing machine. Missing nut on gears (I have a replacement) and I think might have an adjustment problem on the crank. I just don’t have time to figure it out.

The 31-15 was designed as a factory machine. They can be used on light to heavyweight fabrics and even on garment weight leathers. I think the manual says they can be used to make “cloaks.”
These can be motorized, but this one is on its original treadle base with belt.
