The frame had a long term previous owner - He had it repainted about 20 years ago
and told me he paid CycleArt more to repaint it than it cost originally to buy =
The Kestrel Fork was a upgrade mid ownership 

Overall the frame is in Very Good condition 
Typical paint nicks where you'd expect - There is a basic headset included of no value -
I would install a sealed HS  for sure
