While researching an unrelated topic in my books I came across an article about collecting mauser non-gun collectables. It shows the Vernier caliper along with micrometers and other things. The article dates the micrometer to the 1920's. The Vernier caliper shown is said to be in both inches and milimeters with the Mauser Banner and says Made in Germany for George Scherr Co. New York. The article makes reference to a book by Wolfgang Steel called Mauser From Gunsmith to World Enterprise, maybe that book will give more details about the Vernier.- Dave
