In that first one of the spit, what registration number is it. Looks a bit like a question mark

MJ730, formerly owned by David Pennell in the UK, and now by Jerry Yagen's "Fighter Factory" in the US. The aircraft is in 32Sqn RAF markings, and is known as the "Squadron Commander's Query". It's reputed that when the new Sqn Cdr arrived, he was asked by the ground crew which aircraft he'd like (RAF Sqns used a Sqn code, in the case "GZ" followed by an individual letter to identify them). He siad something along the lines of he "wasn't sure" or "wanted to think about it" - and walked out a little later to a Spitfire bearing the code "GZ-?"!

Saw it at Old Warden when it resided there for a while before it was sold to the states
