The Mk I PR Type G was the first fighter-reconnaissance version and performed a similar low-level tactical role to the Type E. One oblique F24 camera, with either an eight-inch or 14 inch lens, was fitted facing to port, between fuselage frames 13 and 14. Two vertical F24 cameras were also installed in the fuselage. The forward camera, installed below the oblique, could be fitted with a five-inch or an eight-inch lens while the rear camera could be fitted with an eight-inch or a 14-inch lens.Matusiak 2007, p.12 A 29 gal (132 L) fuel tank was fitted just behind the pilot. The first PR Gs were converted from Mk I airframes and their Merlin II engines replaced with Merlin 45s. Late PR Gs were converted from Mk V airframes. The Type G was fully armed with 8 × .303" Brownings and retained the armoured windscreen and gunsight.
