Singer used to even own a broadcast transmitter company---Sintronics.They used to make AM and FM transmitters during the 70's.Sintronics also used to make electronic test gear  and electronics for the gov't and military.Guess Singer must have owned the Graflex company at one time-they made lots of AV equipment-mostly for schools and libraries.Somewhere I have one of those filmstrip projectors-may have gotten lost during one of my moves-was surplus from a school.It could also show slides.
