"Soddering finish"? Do you mean a smooth finish to the paint, or do you mean soldered lugs on the frame? Because Schwinns in that period came with 2 different frame types: soldered lug frames, or butt-welded frames. I don't think I've ever seen a 'cruiser' with anything but a butt-welded frame.
FWIW: its a Cantilevered frame he was speaking of. if you look at Thumpism's picture you can see the two tubes that attach to the down tube and arch passed the seatube then become the seat stays. thats the Cantilevered frame style.
