Hi Owen,
your Boss Rook Rifle is pretty rare as a few years ago I had a book on the firm of Boss from the very beginnings to the present day and as far as my memory goes I think it said they only made one or two Rook rifles.
As regards to putting in a 224 liner into the existing barrel I did not mean the slim type used for a 22RF but a standard barrel thinned down leaving enough meat on it to be safely used so my existing octagon barrel could be kept with its name, address and sights.
