Gas tank identification

[Klong]

Hello everybody,

My name is Laetitia, I'm from France and I don't speak German.

I recently bought a gas tank formerly fitted on a R 69/S as a present for my boyfriend. It appears to be in steel but
I don't know where this tanks comes from.

I didnt't find this reference in any special tanks manufacturer (Heinrich, Hoske....). The tanks seems to have 4 "staples", 2 on each side.

Can somebody help me?

Best regards from France,

Laetitia

Here are the pictures:
