SM845
Great photos. BTW I hate to be picky but the second last shot is labelled as Mk IX MH434 – it isn’t. I thought it might be better to point it out while you still had a chance of identifying the aircraft. MH434 is indeed a MkIX, but this pic is of a later, Griffon engined mark – possibly an MkXIVe or F22.
They are nice shots though, thanks for sharing.
It’s SM845 which is a Mk.XVIII
