If you want it, it's yours for the £30 I paid for it.
If you can wait a week, I'm down in Portsmouth on the Tuesday of bank holiday week - we could always meet up somewhere (to save the postage).
The game runs OK but has three lines through the sprite for the player's plane and I can't get sound running.
I can't imagine it's much more than a RAM issue and a duff IC in the audio circuit (or, maybe, more duff RAM).
I picked up the board without realising the EC midi cab we'd seen at the barn (earlier that day) had a P-47 marquee (they'd have made a good pair and, at the time, no one was taking the cab).
