The local village shows round our way had a stall with Asi Commando's and the fun fare at Barmouth had compressed air full auto Thompson machine BB guns, that had to be fired from the hip at a red star target. Llanfyllin show had a rotating target on a driven belt, with a variety of loaned airguns to use. I remember that was the first time I fired an airsporter !
The Royal Welch Fusilers had a recruiting trailer range at Welshpool Show in the early 1980's with rimfire .22 SLR's shooting at Nato type targets and it was free for children ! I have looked for the military specifications for this portable trailer range but never managed to find them, does anyone on the BBS have anymore info, though perhaps it was made in their workshops and didn't have a military type approval, it isn't in the ranges manual.
