Mixed in with my O27 stuff is a box of regular O gauge track. I finally went through the box this morning to see what was in there. After throwing away the worst offenders for rust and tarnish, I'm left with 21 pieces of curved, 22 pieces of straight, and one 90 crossover. It's dirty and some peices have just a touch of rust on them. However, a good cleaning would make for some nice usable track. What would be a fair asking price for this?
