Set of vintage stainless steel bowls marked Hamilton Beach, for an old Hamilton Beach kitchen mixer.
These aren't marked with model numbers that I could see, but sizes are 4 1/2" tall x 8 1/2" diameter x 4 3/4" across the fitter for the larger bowl, and 4 1/2" tall x 6 1/4" in diameter x 3 1/4" across the fitter for the smaller bowl.
Both of these bowls have fine scratching from use, but are clean and nice overall, no dents, very shiny.
