I'll just poke a few holes here .... Theoben / RAW in the world of PCP's these past 25+ years are by in large changed up very little as there a dinosaur in a world of other species evolving around them.
Yet .... they to this day more than hold there own and folks still wish to purchase & own one or several of these excellent PCP air rifles. May I Have Another Please
I totally get BSA, Webley, Diana etc for there Spring piston style air guns as the most used platform in todays world is PCP.
BSA made a couple PCP styles but were less than service friendly and solid enough when assembled to take real world use & abuse ( relative to other brands )
Diana in PCPs went China ... nuff said there.
Webley far as I know never danced in PCP's
