There is a mint walnut stock for sale at Gary Canes, (
info@tech-wood.biz) speak to Jane, to fit a Webley FX. It will need a hole drilling for the Pressure gauge and another for the second stock screw to fit the later Swedish FX2000, but it's an easy job and for a Walnut stock of this quality, it's well worth it - mine was £275 delivered.
Alternatively, I have my beech one for sale now, looks immaculate, has two holes drilled for the sling studs, otherwise original .
Regards
Rick
