Well, besides getting dizzy from the upside down pics, it looks to be in pretty good shape actually. The paint looks very good with few scratches that I can see. I see the chain needs to be replaced though because of rust, and a shifter cable looks loose or something, but other than that she looks very rideable. The Shimano 600 is a nice group to. No idea of the model but somebody will chime in on that. Tune her up, wash, wax and polish and she should good to go. Nice bike!
