Probably a hopeless longshot, but I've got an old Hamilton Beach stand mixer I really liked which had a fatal run-in with a metal spoon. Last time, the two worm gears that drive the beaters just jumped out of sync, but this time, it burned down a section of teeth on one. It's a "Deluxe Mixer" model 36-4, probably from the 60's or 70's.

I figure the gear is no longer available, but wondered if there was any possible chance that anything else uses one similar. The beaters are compatible with an old Sears CounterCraft handheld here, so I guess that half was some sort of standard back then at least. The gear itself has "3094-039 8" stamped on it (the good gear is 3094-039 7). It's approximately 28.4mm in diameter with 33 teeth, about 5mm thick, and the smaller shaft that the beater fits into is about 30mm long and 11mm in diameter.

Much Thanks!
