When cleaning out my fathers garage, I ran across an unusual 24" (OK, 23") Brown & Sharpe inside/outside caliper. I would expect a caliper of this size and manufacturer to have a vernier, but this one only has calibrations with 1/8th" and 1/16th" gradations. On the front of the scale it's marked "SELTZER BAU LTD LOS ANGELES, CALIF. U.S.A.", while the back of the scale it's marked "BROWN & SHARPE MFG CO. PROVIDENCE, R.I. U.S.A." along with the B&S logo. There is no vernier nor any place to mount one. Other than the markings mentioned and the scale gradations, there are no other markings on the caliper.
While I can see B&S making custom tools, I can't figure out the use of a caliper of this quality with 1/8" and 1/16" scale gradations. Anybody have any idea who Seltzer is/was and what this tool was used to measure? It will probably be something obvious once we're told.
Thanks, Tom
