Here is a nice lot of 3 Armstrong tool holders. Also an old lantern style tool post holder that fits these holders. The lantern post looks like it fits a lathe compound with a 2-1/2″ wide slot by 3/4″thick, see pictures for measured size. The lathe tool holders fit a 7/16 tool bit. There is a mixed variety of a left hand tool holder a right hand tool holder and a straight tool holder. This would be great for a hobby machinist with big lathe such as bigger south bend, Clausing, Warner swasey, monarch, leblond etc. Has pretty much everything you need to get to cutting minus the tool bits.
