I know! Ii know! I know!
The matched set are for a Hamilton Beach - they would fit models G,H, and K (50s and 60s models) but will also fit the later models from the 70s as well.
The Sunbeam is probably from a Model 7B or 9 Mixmaster but it would also fit the 3B and 5B models as well as the Models 1,3,5, and 7 (although these models would have been originally equipped with a green 'jadeite' bowl).
Hope this helps!!
