Up for bids: a nice example of a 1950s 1960s GM (Buick Chevy Olds Cadillac Pontiac) Window Crank Handle. It is USED (OEM 4151899) in great original condition.  Photos accurately represent condition.  Spin knob is free and turns really smoothly. I believe this handle would be for vent windows only, judging by the smaller size. Feel free to ask any questions you might have. Thanks for looking!
