Hi, I am now the proud owner of an American leather cutter/skriver, like the one here: https://www.yesteryearessentials.com/products/vintage-1920s-cast-iron-american-st-louis-leather-cutter?variant=18230130053. Unfortunately, it came disassembled. Anyone have any idea where I can find any info on it, such as how to adjust it, a catalog, manual, parts diagram, etc.? I'm going to restore it and then use it. Thanks.
