: Who are the big manufacturers of machines that will stitch 3/4" Leather?

The best machines for sewing this weight of leather, were manufactured some time ago by USM and also by Pedersen.

Many companies rebuild these machines as they are not manufactured now, and the best rebuilds I have seen in the world were done by a company called Hudson Machinery Corp. in Haverhill, MA.
Contact Person would be Barry Levine or Steve Sault.
