This old piece of cardboard is a great little tool. Three wheels are sandwiched between two pieces of cardboard. As you rotate the wheels, the color band on the sample resistor change and in turn the ohm values and such also change. It has the IRC ohm logo on both side and the back side has a chart for IRC, RMA and JAN Standard values. Too complicated for me but I would imagine that some people into electronics would find this quite handy. The front has advertising for Federated Purchaser, Inc and on the back it has a 1951 date and also Slide Chart Corp., Perrygraf Corp. of Illinois.

It measures about 2 ¼” high by 4 ¼” long and is in fairly good condition with light wear and soiling.

The pictures are not shown at actual size. Please refer to the description for actual measurements.
