Replacing a platen on my 1930 Underwood 4-bank portable typewriter. The purpose of this video is to show there's more to the platen rod assembly than just a rod: there's a special clip, a partial rod from RH platen knob, two couplers and a stem from LH knob. The inner assembly is for the variable line spacing, done with the push/pull of LH platen knob.
