Water bottles to identify

[Mannlicher]

Hello everyone.
Can you help me in identifying these waterbottles? Period, who used them etc. They both seem to be from the ww1-era and that's why i posted the picture here...



If you have additional pictures with complete ones, i'll be grateful.

Thank you in advance.

PS. the aluminium-one has 1,6 liter capacity and no markings on neck or body
