As above, it's a Vulcan action with no safety catch in a plainer, cheaper stock. It may also have had a slightly lower standard of finish than the Vulcan (though still very good compared to its competitors). Made 1988-2000. Aimed at the youth market.
Unlike the similar Victor, which it replaced, it was a full-power rifle. Like the Vulcan it was capable of over 12 ft-lbs in "export" trim. By 1988, the youth market wanted "full hunting power" and it was a brave dad who tried to persuade his nipper that an easier to cock, less hold sensitive, 9-10 ft-lbs rifle was a better choice than an 11.9 ft-lbs one.
Bit of a forgotten and overlooked rifle. The earlier Victor is a low-level 80s classic era springer, the later Excel-replacement Xocet has a much better stock and slightly improved trigger (and "sexy" carbine options) and was produced until Webley folded in 2006, so has the credibility of being one of the last proper Birmingham Webleys.
Not sure they sold very well. The Excel was not cheap, and I think a standard Vulcan (they were often discounted to compete with contemporary HWs and BSAs) only cost about a tenner more (though that was back when a tenner was worth something
).
I'd recommend a basic lube tune/service. Without a lot of re-engineering, you can't get much better performance from these old things than you will get from a standard spit and polish. And it keeps them true to type, rather than trying to turn a Webley into a Weihrauch.
