imperial russia Help identifying an Imperial Russian belt buckle

[Leclerc]

Good morning gents,

 

I have come across this IMHO rather unusual Imperial Russian belt buckle. There is some kind of marking (maker?) above a double-headed eagle on the reverse but sadly unreadable, at least for me.

 

Does anyone know which unit it belongs to? Could it be related to the White Movement?

 

Many thanks.

This is belt buckle for a student at the Yuriev Gymnasium of Emperor Alexander I the Blessed.
