Ampro Paramount 20 Projector

[lonnieto]

I inherited this Ampro Paramount 20  16 mm vintage projector.   I have been trying to get some info on this model but come up with nothing.  The serial number is 84312. All I could find was the Premier 20 that looks identical to mine.  I cannot sell this item without knowing about it.  Does anyone know anything about this model?  
  please help,  thanks   Lonnie
