That is very neat 'Parashooter'. Thank you for sharing!
I wonder when this 'work holding fixture' came into use? (I wonder how things were done from 1894 to 1904)?
With this fixture, one operator, doing 120 serial numbers per hour, would average 30 seconds per action, in 1917.
The operator would have to 'clear' the fixture, lock an action into place, properly index the action, andwork a handle to ratchet feed the work through the fixture as a six or seven digit serial number was hand-stamped on the receiver. (If I understand correctly).
I can see how the depth of numerals might vary, depending on force of the hammer strike.
If the digits were done one at a time, I am guessing there would be some 'screw ups' and mistakes.
Seeing drawings of actual tools and fixtures (and trying to comprehend the function) is quite interesting.
