unknown sight for small arm or grenade launcher?

[bergler]

Got this interesting Little aiming device, whereby I do not know what it is ;-)

Seems to be an attachment to a rifle or similar. No markings found, only the numbers for distance I guess.

I think it might be WW1, and austrian origin or similar. Maybe for a grenade launcher, but I did not find anything on the net.

Any help appreciated!

Looks very similar? If so, then an Austrian M95 grenade launcher sight from WW1 as you thought.

Wow, that is it!!!! Where did you find taht pics??? Any more info on this?

Is the mounting ring part of the sight or the Standard ring from the rifle???

Brilliant, thanks!
