Great info. I have what I believe to be the same set up; Schwinn cranks and forks & the Huffy frame. This one was so rusted that I still am unable to get the rear gooseneck out of the tube. The nut broke off so I just drilled it and will use a “tap & die” to thread and put a smaller nut in to...
I have this tandem, which I’ve had for about 30 years. It was always black and rusty. I recently stripped it down and painted it. It had a Schwinn name plate & (what I believe to be) Schwinn cranks. But I think it may actually be a Huffy.
The serial number is:
505-459910. (See pics)
there is...
