This is a Halifax B Mk1 Srs1, the first production model of the Halifax. Points to note on these very early Halifaxes are the wavy camouflage demarcartion line half way up the fuselage, the lack of a teardrop observation blister on the side of the nose, aileron mass balances on the lower surface and Handley-Page slats on the leading edge - all of which were quickly changed on following variants.
Possibly photographed at Air Fighting Development Unit, Duxford, UK, 1941-42
