MKI rifle and MG stowage

[Bruce Parker (RIP)]

I take it the rifle boot and Bren tripod socket were original? They sure look like it.

As to the smoke generator, your height was 15 cm or 6". By scaling the (accurate, I think) dimensions from the drawing above (Coventry manual), the generator rounds themselves are about 4" tall. A 6" tall box would take a 4" tall item with room for the felt padding and space at the top. I vote that this box took two rounds.
