Identification Heer and Luft tropical buckles

[saruman]

Hello,
I would like to know please if these two buckles (tropical models) are original or not. Thank you in advance !

Both buckles are original, I think that the Luftwaffe buckle is Assmann made and G Brehmer is the Heer buckle maker

Thank you very much for your answer ! I didn't know the makers, thank you !
