Sears Kitchen Pentel

I find it interesting how this listing comes with a cleaning instructions sheet but the photo on the sheet is also a Sears Kitchen branded Pentel item but much older and more interesting.


That looks like an early version of the P205 in the listing, and a PS-350 in the instructions but the separate pin for unjamming is something that I thought only came with the first generation of the Mechanica Graph (the progenitor of the PG5) before it was integrated into the button.
