Hard to tell for sure. Right now it is a 200 amp setup but the panel may be rated higher. I am guessing it is not any higher than 200 amps.
 
Got to give the AHJ some proof for 200 amp after load calcs

Any clues as to how I can look for manufacturer or the bus rating, the tags are long gone, but this setup has been in for years, still do not want to overate the bussing if someone slipped a second 100 amp on to a 125A busbar? The 2/0 tells me it should be 200 but I need to do some detective work.

Probably some off-brand meter pedestal mfr, like Midwest. Myers Switch in SoCal used to sell them up here too, as well as Delta Switchboard out in Stockton. Delta is out of the business, Myers is doing different things now. But for a while in the 70-80s those companies made Meter Pedestals, with or without mains, because of all of the different USERC and local requirements being difficult for the big national suppliers like GE, Sq. D, ITE and Westinghouse to keep up with. Over time the big boys caught on and the small local suppliers died out.
 
Knowing actual rating of that piece of equipment is one thing, but nothing wrong with supplying 2- 100 amp service disconnecting means with 175 amp conductor - as long as the calculated load is 175 amps or less.

Now if this is a single family dwelling then 2/0 would be allowed for 200 amps per 310.15(B)(7). The two 100 amp feeder circuits can not use (B)(7) though.
 
Wait, I've seen this one! Lemme see what I can find.

[EDIT: Sorry, nevermind. The one I had in mind is a bit different, has a 200A MCB ahead, and ... it's also missing the label anyway.]
