Bikepedia reference

I picked up this bike at a garage sale. As far as condition goes, there are some chips in the paint, a moderate amount of superficial rust (especially on nuts and bolts), and the bar tape is torn. Also, a previous owner added a front brake with interrupter lever and replaced the tires (with Shwalbe Marathon Plus, worth more than I paid for the bike by themselves!).

Some questions:

1. It has a flip-flop hub with a 17t cog on one side and 18t on the other -- both fixed. Is that how it's supposed to be, or is there a freewheel in there in need of some PB Blaster and grease?

2. How much is it worth? Unfortunately, it's a size 57 frame, which is too big for me (I'm 5'10"), so I'm going to have to sell it. (Unless one of you has a comparable bike in a smaller size and wants to trade!)
