I keep looking at the holes. You are probably right about ORBs, but the one on the left seems a little larger - Lenin? (You can dream, right? :thumbsup) I'd just see which two fit in the space.
Here is an example of the special tunic for NKGB Commissars.
It had two different types of damage / staining; the first, mostly in the upper part of the tunic, was from rain. That cleaned up over the past three/four weeks quite well. The other damage / staining was, I am told, from food. Seems this Commissar was not the neatest and spilled a least one meal into his lap after perhaps having 'one too many'. That staining is much tougher to get out without using heavy duty chemicals.
Due to fading, the outlines of the two orders (see previous posts) were easy to see; a Lenin and Red Banner worked perfectly. Nice to know what he was awarded.
The work that was done on the tunic took much of the staining out of the exterior of the tunic...however, you can still see it when looking at the interior.
