Description: |
| An example is reported that matches the patent drawing and is marked with the patent date plus "J. SHINDLER & CO. / RENOVO, PA". That firm operated a grocery and dry goods firm. It seems most likely that the inventor or someone else actually made this angle attachment for a bit brace, and it was sold through a local store. |
