I am curious how many of you have seen these boxes in your collecting travels? I have not seen them in the past. Do any of you have them in your collection and if so do you have any pictures or further data on them? Does anyone have pictures of them being used by radio personnel in the field?

1st Case - Wehrmacht Case "Fu 23 Anodenbatterien" for field radio equipment?

2nd Case - Wehrmacht Case "FU 52 Schreibgerät" contained a writing device used by radio personnel?
