DURANT 99 Inch Rotary Scale; Each 360 degree turn = 1 inch with 1/64" devisions

Description

This auction is for a Durant Rotary Scale; it measures in inches;
Each one  360 degree turn of the 5/16" dia. input shaft (that sticks out the bottom)  turns the counter dial one turn or 1" measured  in 1/16" increments
(with line divisions of 1/64" between each 1/16" fraction)
Unlike a normal counter, it can rotate forward and backward
Reads from 00 to 99 then rolls over to 00 again, so you can measure longer than 99".
It works forward and backward equally well
This is new old stock, so it is a little dusty, it probably would not hurt to remove the cover and grease everything inside before using it
