Russian badge- Aeronautics

[pantini]

Hi,
I bought recently this Russian badge. I traduced the inscription- The force and the honor of the Aeronautics. But I want to know more about this badge, someone know what it is exactly?
Thank you in advance.

Pre-WW 1 donation jeton to recognize those who made financial contributions to military aviation in Russia. These were given out to donors on a chain so they could be worn by looping them over a button.

I've never seen one of these that was converted to have a pin on the reverse but that's what seems to have happened to yours. Unfortunately, in converting it to a pinback, someone either cut away or filed off the loop at the top of the jeton through which a chain originally fit...

Regards
