I have looked and thought hard about this and TBH the question is answered by the very fact of a cash value vs my opinion of worth.....The cash value is of course what others would be prepared to pay. I would pay up to £300 for a mint example - or at least a +95% example.

My FWB is a lovely rifle and FWB 127/4 are very much an icon of a time, that still easily holds it's own today. Timeless classic on that basis.

It does have an attraction that many modern rifles miss out on especially in the field...it has a quality feel, and this comes through in it's looks and appeal...Would love to have had a Mastersport though !
