If You could post a bigger scan of the stamp, maybe something can be made out of it. But I would guess it has something to do with the post a man who signed it held. And it's Secr(etary) of the Kalininskiy(?) Rayispolkom, Tbilisi
I've done a search on Podvignaroda and I've found a "старшина Киченок Гаврил Остапович" (this is the name and the rank) awarded with ORS (July '44) and OB (march '45). But he was a Starshina in a Machine Gun Motorized Battalion in the 219th Tank Brigade!
