The Starrett 220M Mul-T-Anvil Micrometer with Round and Flat Anvils. This micrometer will handle a wide variety of measurements impossible to obtain with regular micrometers. Such as measuring the wall thickness of tubing. Cylindrical walls from a hole or slot to an edge and many hard-to-reach locations.
I have seen these new go for 280.0 to 125.00
