The mill I have is a ROYL M-80. It comes with different rolls. I
have only seen this model in workshops in Mexico but the model
number may imply other models. I don’t know where it is made
(Mexico City ?). I have seen these in Taxco, San Migual de
Allende and Mexico City. I bought mine in San Migual near the bus
station. I think the shop is named Garcias maybe not. In Mexico
City the Jewelry supply shops are on Piama whicfh runs north and
south near the Zocolo. The shops other than Mexico city won’t
stock much. straight arm casting machines are also a bargin
although I havn’t bought one. Jesse
