Hey newbie here, I have two very old brake shoe riveting machines and a drum brake lathe that belonged to my Grand Father from his Brake repair business. These are from the 30's, 40's, 50's 60's time frame. I don't want them to end up in a scrap yard so where might I find out if there is a value to them and who might be interested in them? They all still work, the riveters have a sanding wheel on the back, still have tray's with rivets! I have all of the adaptors for the lathe for the different drums/races. Any help or thoughts sure would be appreciated. Thanks,
