70s vintage used Mr Pea electric pea and bean sheller. This is a model #800M sheller with a high grade plywood body (birch, I think?) and splined shelling rollers like the newer models.
It measures about 20" long, 12" wide and 9" high and is driven by a 1/15 hp motor. This has been used and has weathering, discoloration and staining to the plywood as shown.
It still has the original paper instruction. It runs, but we didn't test it any peas or beans.
