I believe this vintage tool is called an inside/outside 3 inch caliper rule. It is entirely brass with a little knob on the top of the slide. This is marked S.B.Co. Germany.
It is in good condition with light wear and no abuse. The brass is discolored, it has not been cleaned or polished. Overall it measures 3 11/16” long in the closed position with the rule measuring 11/16” wide.
The pictures are not shown at actual size. Please refer to the description for actual measurements.
