We have a Singer 132K6 walking foot leather and canvas machine

Now you're talking - that's a classic motor trimmer's machine. Built
simple and robust, massive bobbin, easy to use and service. Alas,
they're also pretty expensive, so I bought a Seiko walking foot instead.
Not bad but with a much smaller bobbing I have to reload it more often.
Will stitch 5/16" vinyl, leather, etc FAST.
