That sure looks like the same axle/hub I sent you pics of to me. Offer still stands or, since I tore it apart, I'll sell you just the axle if you want. Also, the hub has good cones as well. Quite often the cones get damaged when the axle breaks.
I do have another. It's on the front of my 52 colorflow. I would sell you that, bike included, for a fair price! It's the black and red model. I'm the second owner and as far as I remember, I have never ridden it.
I'm a Schwinn guy.
I would also trade it for some hard to get 36 Schwnn parts....
