What's this optic sight ?

[Julfrenchie]

Hello guys,

I was looking for an RA35 sight for my mortar, and i've found one with an additionnal sight, but i don't know what it is. Maybe one of you know that.

If you know the exact name in the german period manuals, i'm interested.





Thank you

Regards
