|
|
Description: |
| Improvement on Pedersen's January 30, 1894 pat. no. 513,619. The heads have grooved sides with teeth, and the end of the handle has a curved slot with matching teeth. This allows the handle to be adjusted in relation to the open end.
A 1906 "write-up" describes six different size heads for one handle. A 1907 product announcement gives the brand name as "FERRET." |
