EXQUISITE EARLY HEINTZ BROS JEWELERS / RING MAKERS GAUGE

3 1/4" long. Heintz Bros were Buffalo, NY jewellers. This piece is stamped with very small letters on the back 'PAT. APPLIED FOR'. An example of this piece is shown on page 99 of the book 'TOOLS RARE AND INGENIOUS' by Sandor Nagyszalanzcy. The brass Buffalo and fancy etched lettering make for a very beautiful early tool. Uncleaned as found. This piece is brighter than what the photos show. The photos are a little dim.
