Aschmitz

I was given a Rex 11-155r fairly recently and this is my first industrial sewing machine of any sort. I've been trying to find more information about the machine and what it can handle as far as leather goes, but I'm not really pulling up much at all. First thing I did is put a servo motor on it, now I'm just trying to find out what I can do with it and what all I need to make this work properly. I'd really appreciate any information about the machine
