Another mystery frame from the archives of my life. Italian threaded BB (tape on ST says 35-wrong!) and headset, 70mm BB shell. Unmarked dropouts front and rear. Repainted and chromed or rechromed. Markings on the frame set: 1445 (?serial number?) and 50 (ST size c-c) on the BB shell; "SWALLOW" (my birdbrained opinion) pantographs on fork crown and stay caps. Seat post size is marked on frame, but can't see in photo. Previous owner thought it to be a "BMZ", I know it is not. Any input is as usual very much appreciated.
