Well I had a spare few minutes in-between coats of paint drying, so done a bit of a mash up, I've managed to fit a BSA Lightning action into a Superstar stock, although there's not a huge amount of difference between the Supersport Custom stock and the Superstar stock, it comes up to the shoulder a bit better and points really nice, the Superstar stock is slightly chunkier and about two inches longer at the front, unfortunately the front stock screw holes don't line up, so it might be the case of drilling new holes, filling in the old ones and just spraying the stock black if I can't get the filled holes to match the rest of the wood, a bit of wood needs to be removed here and there and a cocking channel for the articulated cocking linkage needs to be filled in and created, so the gun can be cocked, an interesting project for the future.
