Check out this very rare early Hamilton Beach milkshake mixer from the 1920s. I believe the model number is 4N, but I do not see it marked. This mixer works. The cord is original and it's in good shape. A little stiff, but no breaks in the insulation and it hasn't been taped. You push down to switch the motor on. It's a little stiff but it works, you can feel the springs are good, it just needs a little lubrication. Very nice porcelain over cast iron base. The porcelain is not chipped. The Chrome or nickel finish is in pretty good shape and would shine up very nicely. I do not have the mixing cup. This is a terrific find for the antique Hamilton Beach milkshake mixer collector.
