Late 80's Vulcan variant.
Vulcan without a safety catch, and a simpler stock design, most components interchangeable with Vulcan.
Marketed as a youths rifle / light weight hunter when launch, also used "silent spring" tech - (a nylon spring guide, they worked but didn't last forever, plastic on them eventually deteriorating)
Came out a little after BSA brought in the Superport which it undercut by a couple of pounds.
Had one new, very handy field gun, simple trigger that was never going to win it any championship points, but compact enough to carry round a wood all afternoon.
I'd guess 7lb ish, so light as full power springers go. - you need a gym
Chambers will have a part diagram you can use as a basis for a strip down, any article or video on tuning a Vulcan will be relevant for getting the best out of them.
