Skippy and Tankie............... A querie.......... I was thinking about the jammed in return spring nut. I seem to remember that if it did jam up tight, say rusted in (the salty water from the swamps up in Queensland used to get down the tube and rust the nut to the tube as I remember.....) If you use the 'appropriate amount of technical force' and the return spring unscrews from the TMH (the trigger mech. housing to you heathens and pagan savages still out there in the colonies and antipodes), then for some reason, the bloody tube is then jammed up in the butt. It'll rotate OK but isn't there a collar that wont allow it to be pulled back and out.

I have this nagging feeling in the back of my head somewhere.........
