Pouches carried in a universal carrier

[mudeng]

After seeing this post, I remember I had a photo taken at the Cobbaton Museum North Devon.
This Windsor is owned by Preston Issac, is a runner, but is overflowing with bits and pieces.
This shows the metal "T" fixing, riveted on the rear of the pouch.
Stowage digrams I have seen list these as ammunition pouches.

By way of interest, Preston admits that this Windsor is not 100% accurate, can anyone confirm the that the stowage bin to the rear of the engine cover is original. Stowage diagrams indicate that there was a stowage bin in this area, and underneath is another mesh screen that covers the prop shaft. Is this correct????
