Thank you Elizabeth, you are just a wealth of knowledge!!
I am really good at taking things apart but putting them back together...not so good. The machine was damaged when shipped to us so pieces are broken off and it locks in one spot when turning the wheel. No parts can be found or info on the machine, we tried several sources and even the museum did not have this mach or info on it. The manual we have from the 1800's in all in german.
