So when I got my lathe and mill home, among the tooling and other miscellaneous items was this v block. I have looked everywhere I can think of online to find a match and stumbled across an identical one on ebay. Turns out the seller said it was an old listing and he had no idea what happened to it. I was bummed because I really had hoped to have a matched pair. I know this might actually be a fun and very educational project for me to just make one and, being new to lathe and mill operations, it would probably be great practice. However, if anyone has ever seen one of these or has an idea where I might find one, I'd still like to pick one up in the meantime. There are absolutely no markings on this anywhere to give a hint as to its manufacturer. I'm totally stumped.
