Northern Electric N1293-GP Wall Telephone Set Schematic

[Ktownphoneco]

Hi All   ....     Please find attached a schematic diagram for the Northern Electric N1293-GP  (293-GP) common battery wall mounted telephone set equipped with a "radio frequency (RF) filter.    Schematics for N.E. 293 dial sets is very hard to find, probably because they weren't included with the set when it was sold to the various telco's.   
I've attached the diagram in two formats, "jpeg" and "pdf".      The page size is "8.5 x 11.0", standard letter size.
