Hi can anyone give me an idea of value please on a Crosman M1 with wood stock. I know these are rare and think the wood types were only made for about a year ,1968 ? before production to the plastic stocks. This gun isn't in bad nick though it looks like the stock has had a re varnish and there is a long scratch on the left side. Paint work is quite good on the action but has faded on the barrel. The magazine is the wooden type of replacement. These were never powerful and testing it today I found it will shoot a bb through an empty shoe box at 10 mts.
