Help fixing my BSA Super 10

The trigger mechanism looks like its seperate to the hammer workings. I cant work out why me taking out the metal rifle from the wooden stock would make it all come tumbling out. Thanks for your help I really do need and appreciate it.
The stock screw has become stuck in the lug that holds the mainspring and guide in and has just unscrewed it allowing spring and guide to make a bid for freedom
This part should be still in the action holding the spring and guide in

That looks like a metal...mine is black nylon or plastic...but yes you have identified the bit under the stock screw.
 
The parts you've lost are the hammer spring and its slip washer .
And the detent bearing and its spring they are a bit of a pain to resemble leading me to believe the small spring and bearing you cant find were not reassembled the last time someone was inside it.

Even when the stock screw is removed the black nylon spring guide remains with the rifle and is held quite firmly in tension with the bearing and its spring . It goes back in with quite a snap / click when reassembled correctly.

Dont stress , take a moment away from the thing then watch the strip down video on YouTube.

You'll get most of those parts from j knibbs or chambers or even the bay of evil.

Just read @Richie# post above .

I can visualise it now hes quite correct . I forgot theres the lug between the hammer guide and stock screw.

That guide is quite soft plastic and prone to stripping . And the stock screw has turned the lot free 👍

Thankyou for your replies. Yes the luttle spring and ball bearing are gone..its the triggee screw holding it in...i managed to get it all togethor and filled the buddy bottle then screwed it into the regulator valve and the air came gushing out again...i am wondering if its catching on the stock inside where I cannot see. I will try again in a few days. Thanks again.
