I have an Arcade Crystal coffee mill that is cast iron and it does not have a number on it. Everything I see for these Arcade items have a number cast into it, but I can't find a number on this anywhere. I was considering finding the real glass jars but without knowing the model I don't want to pay the high prices and then it not fit! I would love some information if anyone has knowledge about these. I did order what I thought was a repro of the catch cup but it did not fit well so I not going further into restoring until I am sure of the model. Thanks if you can share some information.
