Meters that are very old will not swap into new meter sockets.
That said at most we are taking a day or two, most times I would use doubled solid 10 AWG copper.
This would provide 80 amps capacity, these are "free air" conductors so you use table 310.17 which rates 10 AWG at 40, run twice that is 80.
I am not saying this is right and if this has gone on two years these folks surely know they have not been paying, They will pay now
Once this is made known to the power company they will back estimate usage and will expect payment.
As to you question on how much load the conductors are subjected to all depends on what is turned on in the house.
I see eight Branch circuits worse possible case they are all 20 amp circuits loaded to 20 amps each all at the same time. (not to likely)
Half of these circuits draw through the right hand jumper the other half through the left hand jumper.
That all being the case the load through one of these jumpers could be any where from 0 to 80 amps.
Having been there for two years already and still looking fresh I would say the load has not approached overloading the wire.
