Armstrong No 00B (Maybe 008 or OOB?) 1/2" boring bar holder, shank is 3/4" x 5/16". It has an Allen head screw to secure the boring bar, which I'm not sure is original, but it works fine. Someone has tightened this in the tool post way too hard a couple of times, causing the top, and to a lesser degree, the bottom, to mushroom. Depending on the width of your tool post, it may fit fine as-is, or it may need a quick filing to thin out those widened areas. I've never used it, as I don't have the appropriate tool post, so everything here is based on a visual inspection. All items sold as-is. Everything I'm selling came in various machinist lots from estate sales, auctions, trades, etc. Most of these pieces have not been used by me, so what you see is what you get. See my other auctions for other vintage lathe tooling. I'm cleaning out my tool boxes of pieces I don't use to make room for things I will. Thanks for looking.
