Great. We eagerly await the birth of the BSA ShedSporter SB.
I like the early Airsporters. the Mk I & II. The conical breech exempts them from conversion though, so I suppose a late BSA Airsporter-S with the heavy barrel would be the optimum for sliding breech. I wonder if there is enough room in there for making a 22mm longstroke, to give low recoil etc?
