Patent model for stamp cancelling machine

Description (Brief)
This patent model demonstrates an invention for a tool for turning a sheet of metal into a printing plate while writing on it. The air-powered writing instrument made a series of sharp blows to the metal, knocking out projections on the back of the sheet. The projections formed a facsimile of the writing in reverse and in relief for printing at a type press. Maker, patent number, and date are unknown.
