I need some help-a strange pin fell out of my rifle, now it won't fire...

Hey Y'all.

I was out shooting my Webley Raider yesterday (practicing for the Pyramyd Air Cup) and having a blast, when suddenly my gun wouldn't expel air through the barrel. I cocked the gun several times and pulled the trigger which only yielded a click, no puff of air which to me indicates that the sear of breaking. I then looked down and noticed that a "pin" (I'm not sure what exactly it is, but it is a small steel rod, about 6/16ths of an inch long) had fallen out of my rifle. At first I suspected this was a trigger pin, but the trigger functions fine and when I removed the stock I could not detect any absent trigger pins. The pin has a small protruding head that is a smaller diameter than the rest of the pin (I tried to highlight this in the pictures). I have not taken the rifle completely apart yet because I do not posses the tinkering prowess to do so with any resemblance of confidence in my self-I'm having one of my shooting buddies help me with that.
This is a huge bummer because the Pyarmyd Air Cup is fast approaching and would like to know my gun is in working order before then. Does anyone have a clue as to what this part is and how I can remedy this? Perhaps it is a part of the hammer/valve assembly?

I'll post pictures and a link to the schematic for my Webley raider.

Thanks,
Nico

Here's the schematic (disregard the Magazine Unit portion in the upper right, mine is the single shot variant):

That's interesting that the link only shows pictures of my R10, when I click on the link there are numerous pictures of the raider-I'll try to sort that out.

Yes, I found the pin on the ground while I was shooting-before I took the stock off the rifle.

The exact model of my rifle is a 2001 Webley Raider, single shot that manufactured by FX.

Thanks,
Nico

Last year something crazy like that happened to me AT THE SHOOTOUT THOUGH! So had some professionals looking at my rife, with negative results...just sucked! Packed up an left.

Hi Nico
You can take a picture of the part more clearly. Thanks

Thank you all for the replies.

I diagnosed the problem with the help of a buddy of mine at the shooting range today. Apparently, the valve stem physical broke off from the rest of the system. Damn. I did some further research and discovered that this was the "Achilles heel" of the Webley Raider. I believe I can order a replacement from England. 

Looks like I'll be using my back-up rifle at the PA cup.

Once again, thanks for all your help.
Nico
