Vintage Cast Iron Hand Crank Grinder Sharpener Parts Restore Gear 509

Vintage cast iron hand-crank grinder/sharpener. Hand crank with wood handle drives a large red-painted gear and pinion; the drive shaft and wing-nut collar are present but the grinding wheel itself is missing. Gear bears a stamped number (partially legible — see photos). No maker name found.

Sold as-is for parts or restoration. Heavy cast iron with old red paint remnants, patina, and surface rust consistent with age. Crank and gears are present but operation has not been tested. Please study all photos to confirm identification and condition — what you see is what you get.
