Dustin,

Thank you for your kind comments and the very helpful “exploded view” of your lovely G gun.

You are quite right to describe the part as a cocking limb as it is of one piece with the tumbler.

I will carefully avoid tinkering with the works, or any dismantling at all if I can help it. I do plan to try re-browning the tubes without further striking down.

Does your top lever hold open? I thought that the stud I mentioned was necessary to keep the cross-bolt clear of the bottom of the descending top extension.
