Does anyone know who makes this device? I have an older one and am very bored, so I thought I would kill some time and restore it to new/better condition. I searched online and it appears Mueller's has the most parts but does not show the leather burnisher or the company decal both items I would like to replace when I do the polishing and cleaning. I have found that I can resharpen the blades and make them far sharper than new ones. Any help would be welcomed!
