THanks for that A and C.
FNG, I've just spoken to the owner and at the moment they have no space. However a Rheims Rocket that is currently there is due to move shortly and a space will be available. If you drop Bill Bowker a line on 01438 355051 then he will let you know when the space is free.
Unfortunately, the maintenance is for Private C of A and PFA types only I'm afraid.
