STBO Hot Date

I've been sitting on this one for a while. There's a few issues. The rear steering is completely locked up. The eccentric front crank assembly is gone. (neat way of tensioning the front chain) and the rear axle screws are toasted. The whole frame is badly pitted and I'm thinking some fork parts might be missing. Project bike for sure but I'd be happy with a roller...

1890s Colsen I think...
or something similar.

Wow! I’m not 100% sure I understand what I’m looking at.

Bit of a rare bird. Should be interesting to see how it goes.

I got the headset apart with just a little effort. But that rear-steer headset is a no, and I'm not the first guy to try to get this apart. I did get the bearing cup to move and the top race will move but the threaded inner is froze solid. The bottom half is alien to me, I don't see where a bearing would even be. And the set screw for the cog is gone and it still don't move...
