Vintage Original Kitchen Aid Model A9 Coffee Grinder Complete The Hobart Mfg Co. You are looking at a vintage KitchenAid A-9 grinder. The red grinder selection does move but when it gets to medium it rubs against the burr inside the cone.
I can see some burr teeth missing. I believe this is one of the earlier models. It was introduced in 1938. The jar while being in great condition is kind of useless.If it was full of beans it would be hard to screw on the base without losing a bunch of beans. I believe they replaced it with the ones that had a lid on top.
It stands 13 1/2 tall and the jar is about 4 in diameter. The pictures should show details and condition. I had someone write me about this grinder.
You have the Holy Grail of A-9 coffee mills. Your example is extremely early and has the nearly impossible-to-find single-opening bean jar with the decal on the top and the original rubber gasket. This is the version that appears in the 1938 magazine advertisements. The bean jar is actually pretty easy to use. After filling it to the brim, you simply invert the base unit and hold it in place on the jar while you rotate the jar to engage the threads.
Your grinding elements may simply be out of position and may have coffee grounds under their seats, although it looks like the machine screw in the center, which also vibrates the unground beans to help them flow into the mill, may not be original. Amazingly, new grinding elements are still available from Hobart / Kitchenaid and are relatively inexpensive. I bought a pair earlier this year.
