Item MA15 - Joshua T. Slocomb Co. (Providence, RI).  Thread Micrometers No. 29 & 30

This pair of 1-2 thread micrometers represent the two styles made by Slocomb.  The No 29C is used primarily to make taps as the same diameter of another tap or screw, or to cut screw threads in a lathe to fit a particular nut.  The No. 30C is designed to measure accurately screw threads.  Both of these scarce micrometers are in the seldom found 1 2 size.  Both have lost most of the original black frame finish, but are only lightly tarnished, have no rust or pitting, and work smoothly.  Good+
