Back in the very early 80s Trapshot days, Venom offered custom BSA Mercuries and Airsporters.

There's an old ad in one of "troubledshooter"'s galleries (links in his signature block) showing a Merc with a Monte Carlo stock, and an Airsporter S with a Tyrolean, in classic early Venom style with swoopy, capped, pistol grips, big ventilated recoil pads, and lots of stippling. Alongside the more well-known HW35, 80, 55 and FWB124/127.

So they were made.

I can't remember ever seeing one, reading a magazine review, or reading about them on here.

Anyone know anything more? I wonder what they were like to shoot, and what happened to them (even if there were only one of each!).
