If all else fails hunt that Meyers fellow down, he seems to have disappeared. I think he was looking into have some bowls made. Not that I remember what they were to be for, but he got into how they are made with metal spinning I think it was called. No idea of if you need to make 100's of them to get the price down or not.
A few years back I was at the LeSuer swap meet and there was some reproduction cups floating around for Allis machines and they looked the same as the Vortox type, so some one is capable of producing them.
Hello Ray54, I've been keeping an eye on you, the bowls I had made were for the 2 Ton aircleaner, not the oil bath type.
