Don't forget out old Mk IX with the Mk XVI gun setup

Anyway, just for fun, when the first squadrons of the Mk IX entered service in 1942 (february?), one squad leader lined his squadron in battle formation, cruising at 43K. Nothing the Germans had could be thrown at them at that altitude at that time.
I wonder how well AH models this, but in real life, nothing in the planeset could compete with the Mk IX at very high altitude, - being from 1941/42 that is.
