Iain,
Making a rare post on LSP, can you PM me, I have some pics that you might find useful.
E.G This is one of the few red/white grey a/c with the new nose
Could it be a Blenhiem? Absence of cooling intakes on top of the cowling and what appears to be an underfuselage gun pack below the wing?
The other shot could be a Marlyand.
