No prob's SD 'tiz easy done
Edit; Evening Graeme, I'd say that the airframe looks like a Bell P-39 Airacobra, but dunno what that "thingy" is
, it looks too constricted to be a cooler/filter intake and that looks like an exhaust pipe at the rear so maybe an early rocket launcher pod?
No time to look further now, maybe someone else can ID the variant properly and I'd have to call an OH anyway as I don't know when I can get back today!
