After looking into it a little more, if I had to go out on a limb and speculate who or what Ostashkov Industrial Inc is I'd say the most likely candidate is the Ostashkov Tannery I mentioned before.
For the most part Ostashkov looks to be just a small Russian fishing village and the Tannery is by far the largest and most substantial business located there. So I could see the Tannery ending up as a subsidiary of Ostashkov Industrial Inc. IMO.
Of course I have no idea, I'm just speculating but considering the Ostashkov Tannery is one of the largest in Russia I could see that being it.
Going to have to wait for more details to know for sure.
