Review on 📏 Starrett APT436 1XRL 1 Micrometer: Precision Anvil Spindle Range 0001 for Accurate Measurements by Tim Burns

. First, I was able to buy a new 0-1 inch mic for a few extra dollars. The mic I received was an asterisk and the serial number is 60si. Use it on turbines. Labor and other important measurements, and as old as this vintage mic, it hasn't changed a bit and works as good as it came out of the box, new, it all needs care and will last a lifetime, buy it once!
