Hi steve, difficult with these bb guns especially in todays climate,the plastic stocked version ,not as sought after as the wooden version but still desirable..the blue book gives a top price in good condition as $150 ,i think you can equate that into pounds though over here and say £150 -£175 ,and a nice woodstock one should sell for about £200 -£225.. i have a few of theser and love mine, brings back my youth when we use to play soldiers and shoot each other , health and safety in them days was not even heard of!..
