Leather cases i.d needed. Which nationality? Experts please.

These four items are driving me crazy . I don't know which country isued them and when. They are top quality with thick stiched leather with brass and copper rivets. The only markings are A.E.

1) A large spade case.

 

next is a small rectangular shovel case

 

third is a small pick axe case , or maybe a pionnier axe, or a regular axe case .

 

Last but not least is a small thongs case (or other similar tool)





Any info which could positively identify them will save me from many future nightmares.

 

The only thing I know is that they aren't from SFR Yugoslavia for sure but that's not much of a help, is it? Let's wait for the right answer.

 

A real mystery. They are excellent quality and not recent, but Ican't find anything similar.
