Ok, thanks. The bigger trigger is on the slightly earlier model with the steel tube spring guide.
They must have done some improvements on the slightly later omega, improving its feel and lowering its weight
Cheers!

There were definitely two versions of the trigger.
They are mentioned in Chris Thrales’ book, where he says that the Eclipse u/l (introduced in 1988) used the “perfected unit as had been used on later versions of the Omega”. Which suggests that the later trigger came in no later than 1988 (Omegas were made 1984-1994).
As I recall the modified trigger was available, direct from Webley,around a year after the rifle was introduced, I believe the "Nylon Darning Needle" spring guide should have been fitted from the start but a steel guide was fitted due to supply problems.
I had a clear out a few years back and give the purchase paper work from Webley to Chris Thrale otherwise I would have been able to confirm dates.
Still have and shoot my Omega very nice gun
Lots of useful stuff appearing on here, in answer to one post I will try and add photos of some of the trigger parts that are in the Omega I am trying to sort out.
The trigger has indeed been modified in that a tiny coil spring has been fitted into it, this is at the point where the front end of the lower leg of the rear sear ''touches'' the trigger. The trigger spring proper was so badly bent it just ''floated about'' and did nothing; the trigger adjusting screw has been cut so that it doesn't project beyond the trigger surface [no photo of that]. this means that a ''two stage trigger'' has been created; in that the trigger moves against the little springs pressure until it becomes squashed and the trigger then touches the rear sear's front edge; the upshot of this is a monumental change of leverage and it takes no feel-able pressure to discharge the gun; in fact it will self discharge on closing the barrel, or at random before that!!!I have now fitted a new trigger spring and a longer trigger adjusting screw, this now gives a longer '' one stage '' drag type trigger action with variation by adjusting the screw in the trigger.
However the trigger is still extremely light and I now have a new rear sear on order, hoping it will resolve things. I think that the overlap portion on the rear sear has been reduced to give a lighter let off, as the front to rear sears overlap is almost non existent; I have now had this trigger apart so many times I can almost strip and re assemble in my sleep so any advice I have I am only to glad to pass on if anyone asks.
Please have a look at the photos and let everyone know your thoughts.

Your main sear looks in really good condition, the sear face is still flat & crisp with no visible damage (in the photo's). The auxiliary sear doesn't look too bad either but the pics aren't quite as clear.
I'd check the sear face of the piston slot. I had an Omega which had this face butchered with a file, presumably to lessen the release angle and reduce trigger pull. It was an epic fail, still worked but trigger functionality was terrible. I had to re-cut the sear face on the piston to the correct angle and re-harden.

Your trigger is quite different fom mine, so I can't comment on whether the coil is original or correct. The trigger adjust screw appears to come through the trigger at quite a different angle fom mine.
I agree with Greg, though, that your sears don't look as if they've been messed with, and his point about the latching on the piston is a good shout.
Thanks a lot guys; I did get a new rear sear and the projection of the overlap [top face to front sear engagement] was a lot more than on the one in the gun; I haven't checked the piston as the difference on the rear sear was old 0.5mm to new 1.1mm, ouch!! fitting a longer trigger adj. screw also altered the trigger beyond belief; there is now no first stage and the let off pressure is much higher; also the gun doesn't fire with the safety catch on [BIG BONUS].
I'm now going to trial the gun a little to confirm it's safe and then we're all good.
Many thanks for the advice and I'm sure others will benefit too.
Cheers
