Err... maybe it was a cheap secondhand rifle for you but the Webley Omega was the flagship model for Webley, when they finally went after a good trigger, a solid precision breech set up and some good sights and stock. It was built to compete with the Feinwerkbau Sport, so its a bit like the Anschutz 335 and BSA SuperStar mentioned above, really a top-level springer.
Glad it shoots well through, they spent a lot on R&D (or stealing ideas from other makers!) on it but it was too late.. the HW77 had knackered everything.
