NOS NY Tel Prototype F57843 loc LP3

Western Electric prototype F57843 that appears to have never gone into service. This phone appears to be the first of what was to be the 1C payphone. Note the connecting tab on the top of the totalizer to choose between DTF and PP (Dial Tone First and Pre Pay) The upper lock is a Manhattan 29A-77 and the vault lock is a 30A. Note the new backboard. Also note the small coin box as found in a 3 slot payphone sitting on a false bottom that can be removed when a standard single slot coin box is to be installed.
