Hello ALL!
I'm looking for any information that I can find on a very old 16mm film 
projector. 
What I have is this, a Keystone Kinescope 16mm, Model E-38, Hand Crank 
reel-reel projector.  It was manufactured by Keystone Manufacturing of Boston 
Mass.
I'm un-aware of it manufactured date & would like to figure this out.  I'm 
also interested in learning its value.
Any info would be appreciated. 
Regards,
           Mark
