Looking for assistance analyzing blockchain of a BTC wallet used to pay out a defunct hosted Bitcoin mining company. Anyone do that sorta thing here?

So here's some background if you want to read the whole story. TLDR: A hosted Bitcoin mining company stopped paying out their miners (I'm one of them).

We are now trying to do what we can to get our machines or equal value for them. If anyone can do blockchain analysis on their wallet address it would be greatly appreciated...

That is their payout wallet but we're trying to find out if we can find their main wallet with the incoming mined BTC. That's above my level of blockchain knowledge.
