Orders of Double Dragon made by Russian workshop GD /ГД/

2nd Class 1st Grade breast star.

Silver, gilt, enamel, coral.
Size 89.51 mm.

What workshop hides behind GD /ГД/ mark?

The base of this breast star is very close (if not identical) to the base of breast stars made by Feodor Rückert /ФР/ workshop https://asiamedals.info/threads/ord...shop-of-feodor-rueckert-fr.23572/#post-348585
Could GD /ГД/ be an independent contractor who worked for Feodor Rückert?

Both breasts stars (FR and GD) are found with leathercloth-covered cases with french legend "Ordre du Double Dragon II Classe 1 Grade".
The interior of these cases bears the stamp of Alexander Treiden workshop https://asiamedals.info/threads/ord...ssian-workshop-of-alexander-treiden-at.23566/
Looks like Treiden supplied others workshops with its cases.
