Stik,
Will be turning up on the Saturday, but not in anything vintage, nor even Yak - having just her back from an engine change I reckon she's better off with the other syndicate members aerobating over Northants rather than sitting on the ground all Saturday at Kemble.
So it will be an Archer III parked at the back of the spamcan zone. I should have AB manning the right-hand seat, no doubt she facilitate recognition of you and / or your aeroplane!
I will keep an eye open for the Pushpak, I've never seen one before.
