Pricing rook rifles that have been rechambered or relined is tricky. Can you add a photo of the bottom of the barrel lug? If the barrel is not marked on the outside, the caliber may be marked there.
Rook rifles are great! ... but if it's not marked Holland & Holland or Rigby then there is little market for them. I once had a very nice Frederick Beesley rook rifle in .297/250 Rook and sold the rifle relined and rechambered to the original caliber with 40 pieces of custom brass and custom loading dies for $1,100 ... and sadly had $1,500+ in it ... ughh ...
