Description: |
| This is a simple caliper with a built-in measuring scale, allowing the gauged measurement to be read directly.
There are two different models marked with this patent date. The earlier is marked only with the patent date, and no manufacturer information. Later examples look quite different, and are marked with the manufacturer information as well as the patent date. |
