notes: label: Description (Brief)
content: A telegraph paper tape perforator, very irregular shaped. A steel base with four rubber feet on which is mounted a paper guide mechanism, tow pairs of electromagnet coils, and a plastic insulator block with four connector pairs. The guide feeds paper into the head which then punches the proper holes. A soldered tube of square cross section channels the punched chads for disposal. A cable ~42" long with a 10-pin male connector passes through a hole in the bottom. No extant maker's markings.
