Hungarian air dropped supplies container

[Dreamk]

I know this is not exactly an air dropped ordnance, but an air dropped piece of equipment, so it may not be exactly the place to post it. Anyway, I'd be grateful to get information on this following air dropped container used by Hungarian paratroops in ww2: - dimensions, weight and exact drawing.

Thanks!

The main thing that is still lacking is the dimensions - someone can help?
