Here's the literature I've been able to find on the 21w180:

Sounds like a combination of the Davis vertical feed and a normal feed dog feed.

Those industrial machines are not worth very much - lots on CL - a lot of business went to China so the machines are all over the place - price $100 and up depending on what the machine is set up to do - if it is straight sew - you are at $100. Some people claim those ss machines sew leather and try to ask more money. Then the buyer wakes up and finds out he should have bought a walking foot sewing machine. A walking foot sewing machine goes for more because there is actually a demand.

One thing I have wondered - maybe I need to get with some of the leather workers. Since the bobbin case was so cheap - I wonder how it would work to set up one bobbin case to just do heavy thread and see how this machine does on leather. It is pretty powerful. I'd imagine it would sew through a finger. I don't imagine it is the thickness but a walking foot moves things through more evenly when you have heavy stuff.

My son has both of these types of industrial machines for sewing tactical gear for his tiny company. The compound feed is a walking foot combined with a needle feed. The upper feet and needle "walk" in unison with the lower feed dogs. In the regular walking foot machine, the upper feet walk in unison with the lower feeddogs
and the needle just goes up & down.
My son was having trouble getting his straight stitch machine to go through around 10 plus layers of a combination of 1000 denier Cordura and binding. We decided that he needed a walking foot machine. We took in a box full of scraps to the dealer to test run several machines. The regular walking foot machine also struggled with the 10 plus layer sandwich. The compound walked through it like it was butter.
Each of these machines has a purpose. Both types are useful, but it is necessary to know which one you need.
