Hjorth Micrometer Depth Gauge in Box Rare!
This is a rare presicion machinist tool in it's original cardboard box and includes the original instructions and two sizes of interchangeable rods. All are in fine condition. The micrometer reads in .001" increments. I believe the application for this tool was designed for is to mount it on a lathe or turret lathe tool post for gauging cuts in process. There is no reason this gage couldn't be used in other applications as well. It comes with 3" & 6.7" rods. A very rare and interesting tool!
