It's not about what it is called. We can go on forever about that or most parts how about a F-strap, battle ship, pistol strap, gun boat its about the safety of that panel and after looking at it, its not that bad. It does have water damage and after removing the breakers the water was setting on them at the time of removal, Because it is in the middle of the field it is subject to expansion of the soil and there is some damage because of that, the buss bars are corroding because of the water and the aluminum has some pretty good oxidation but all of this can be repaired with a little help and the OP has a very good electrician (Not recommended by me but I do know him) that will be working on it and other things like sizing the breakers properly because none are overloaded just over sized for the type and size of the wire that it is terminated to the breaker, sealing the panel so water doesn't get inside and repairing the broken and exposed conduit and wire so he doesn't get any more damage he will be good to go. To the OP it was good to meet you and you have a great place.
