 Up for bid is this Armstrong # 54 precision back gauge. This was the older model back gauge later replaced by the # 76. It is 36" long. I didn't know what it was used for until looking it up on the net. I found out band saw back gauges measure the chord height (distance from the center of an arc to a straight edge) over a set distance. If you Google #76 armstrong back gauge it shows what it does and how to calibrate. This back gauge appears to be in very good condition. The only thing I can see wrong is no glass over the Starrett dial. The dial still works properly. See pictures and bid accordingly.
