Dear Gabriel: Very likely your Spring Motor was always a Spring Motor IF the phonograph body has NO lugs for the idler pulleys that M electric phonographs have to guide the leather belt from the mandrel pulley at right angle to the motor pulley. The other difference is that the M electric will have an indented mandrel end for clearance with the endgate shield. Your serial number is a late Spring Motor as the Triumph Model A in the 'New Style Cabinet' came out not too far higher in serials. Both mica and thin aluminum sheet are readily available from industrial suppliers. The missing 2 minute cutting stylus will be the same as the Edison cutting stylus. So an old Edison Recorder could be used for donor parts. Perhaps the sylus mount for the recorder is on the Bettini patents if you do not have an example to duplicate. Congratulations on getting this rare machine. Kindest regards, Al _______________________________________________ Phono-L mailing list http://phono-l.oldcrank.org
