1920s - 30s vintage kitchen tool, an old hand crank nut grinder with a glass jar. Fun to use and still works well, though its nearly antique now.
I didn't see any makers marks on the top or the jar. It's about 5 3/4" tall overall. Glass jar is good without chips or roughness, and the crank turns easily.
Some spotting but not a lot of rust to the metal. Metal is darkened from age and the red painted wood handle is worn.
