Description: Very Rare Early Brown & Sharpe Manufacturing Company Model 530 Draftsman's Protractor MADE IN USA. I believe that this protractor is quite unique as it has the two patent dates. Note that there are no markings showing logo or model number. Later production was marked with only the later patent date with logo and then the new model 510 designation. A rare piece of history where this protractor was manufactured under the original patent and then marked with the later patent. The protractor is stored in the original plain black paper box. Included in sale is a new copy of "A Brown & Sharpe Catalogue Collection" by Kenneth L. Cope. You may also visit the National Museum of American History web site for additional information.
