I've had this N-S-P auto polish clock for 30-40 years Decided time to see if it will keep time? Short answer no, but will try cleaning the mechanism, that may help? Coil read 900 ohms. Did a group search & a internet search, not finding much on it? My guess is late 1920's thru the 30's? Got any info?

just a cheap poplar wood frame, it is a metal dial face
