It's a longshot but it could perhaps be V7837 which served with 73Sqn and is recorded by Air Britain as "shot down by Bf109s near Bu Amud 23/4/41". At this time 73Sqn was involved in the defence of Tobruk and there was a Landing Ground number 147 at Bu Amud near the coast just to East of Tobruk. You may know that 73Sqn a/c often had very distinctive markings in the shape of a blue and yellow "flash" that extended fore and aft of the fuselage roundel. If you look hard enough it is possible to convince yourself that the cut out in the fabric on the Hurricane is exactly the same shape as the "flash" that 73Sqn used?
