Yes Jim,.....it sez New Jersey Bell Telephone in orange on the base
and the 
drawings are unique to NJBT engineering....not ATT numbers on them.

Someone cut a 4 inch dia. hole in the right side and installed a
muffin fan. 
I took out the fan an put a stainless plate over the hole.  I learned
a 
lesson....leaving the machine on for a few hours, the motor got the
inside 
very hot and the codes from the stunt box, ZA FX and RZ failed to
operate 
the magnet that unblinds the printer.....it just got way too hot
inside.  In 
the morning, after being off all nite, the codes worked just fine
again.  I 
think I have to put the fan back in.
