The closest I can find is a description of an artists impression in the Osprey book on the IS-2. Which states;
"IS-3,Costal Defence Unit,Kurile Islands,1992.
Many IS-3 and T-10 tanks remain in service in the Russian far East in static defense positions.Some of these tanks are still in running condition,but many are completely dug in. This particular example was driven into an entrenchment overlooking the beaches facing Japan to act as a coastal defence pill-box.The tank was finished in a medium green colour, lighter than usual due to the fading effects of the sun, with a larger rolling pattern of medium brown sprayed over it.There were no unit markings since they would be inappropriate for this role."
I would also add that the tank lacks its anti aircraft machine gun and fuel tanks, although the supports are still in place, also the rear fenders are removed.
The main gun is at a steep angle and weathering is fairly extensive,complete with sea gull droppings! the entrenchment is as deep as the top track run and over grown with grass.
Not exactly what you were looking for but may be some help when considering the steppe of the Russian-Sino boarder.
