Pre-delivery portrait of Mk.I K7037 (note the hyphenated under wing serial number). This machine was delivered to 114 Squadron - the first RAF unit to use the type operationally - at Wyton on March 4, 1937. Its engine cut out on take-off at Wyton on May 10, 1938, causing it to crash and killing the three people on board.
Mk.I K7147 was delivered to 110 Squadron at Waddington on January 4, 1938. Note the under-fuselage bomb racks. When the unit took on Blenheim IVs, K7151 was delivered to 5 Bombing and Gunnery School at Jurby, Isle of Man, on November 3, 1939.
Mk.I K7096 was issued to 30 Squadron at Habbaniya, Iraq, in late 1938. With the Italian invasion of Greece in October 1940, 30 Squadron deployed in defence of that country and it is assumed that K7096 had been lost by April 1941.
Mk.If K7159 'YX-N' of 54 Operational Training Unit at Church Fenton posed for a well-known series of images dated September 1941. It was delivered initially to 61 Squadron at Hemswell on January 19,1938 and served with 54 OTU late 1940 until September 1941.

In an attempt to develop a dedicated photo-reconnaissance Blenheim, L1348 was modified with clipped wing tips, faired-over nosed glazing, Rotol three-bladed constant-speed propellers, dorsal turret removed and the bomb bay and other panels taped over
Mk.I L1222 was fitted with outer wing tanks and first flew in this guise in September 1938, in readiness for the so-called ‘Mk.II'. Note also the bombs carried on pylons under the inner wings
By November 1938 110 Squadron had adopted 'AY-' codes. K7151 ‘N-nuts’ was delivered to 110 at Waddington six days after K7147. Like its sister, it also gravitated to the Isle of Man, this time on December 2, 1939.

A pattern camouflage, B pattern was the mirror image, showing the roundel positions: 66 1/2in type A1 to port and the B type conversion to starboard, retaining the outer yellow ring; this was subsequently over-painted
Fighter Command underside white/black finish in the 1938-1939 period. The undersurface was to be half white and half black, however, there were many variations when applied at squadron level. Some aircraft in 1939, had 32 1/2in B type roundels applied under-wing. The starboard wing shows the 36in white serial position, normally carried on both wings, it replaced the original 30in high serials from K7045. The latter were also positioned further outboard, level with the outer edge of the aileron.
