Hey guys,
I have not been able to find an exact match for the 'dimple' location on this part, but while looking I noticed at least 4 different patterns. I think they are representative of early Mk I, late Mk I, and Mk II (2 different manufactures?). Some of them had 2 'dimples'. Some of them had interior formed sheet reinforcement 'panels' (for my lack of a better term) that formed a box structure (for reinforcement of the outer door panels I assume), while some did not. The lack of an exact match for the dimple is why I was wondering if it might be some sort of a modification reinforcement panel or maybe a repair part.
IIRC there was a need fairly early in the life of the Hurricane to strengthen the gear door panels?
