looks nice with the mono stay and internal rear brake cable,it must have been resprayed,i think they where purple and pink when new.this is not really the place to ask for a value
@ matthew71: my apologies for asking about the value. didn't mean to offend. i am considering buying it so wanted to just get a rough idea.
i sort of think it has been resprayed as well.
@ Midlife: you are right! thank you!
cheers for the help, everyone!
It might be a frame for track use. But the unusual long stay is very weird. A good photo from the side of the frame (and from lower lever and not from up to down) could be helpful to imagine the real proportions.
