Is it a Fairbanks Morris ? FMJ would be a "J" type mag from Fairbanks... the B would mean it is a flange mount type mag........... there should be a more specific tag or stamp that has a "6" for the number of cylinders, and possibly another designation for which company used that mag. ............ assuming it is a FM mag.

IF it's red... a power unit, or one of the start on gas/run on diesel IH units... or an earlier M-M. They were used on lots'a things. What does the coupling look like?
