The electro-mechanical specs are the same but the pole piece is machined to fit the cooling plug. They used to be fairly uniform and the cooling plug could be easily fit with a minimum of effort. About a year ago, all that changed - Pole pieces would vary as much as a 1/16th inch. So we now have them machined before assembly.
