I'm putting in a series of photo's just taken to show you a 15-91 is a direct drop in fit, in two different singer treadle cabinets, one with one screw hinge, one with two screw hinge.
these 15- 91's will fold down with out any mods to the cabinet, the lid lay's flat as it should.
same thing using a 66 electric , but must have the thin style motor to close the lid.
this is a 15-91 one screw hinge, singe 6 / 7 drawer..note the lifter is missing, which has nothing to do with fitment of a machine head. normally houses a singer 27
for some reason most my photo's are not loading again
