If you look at this pic, and the panel on the rail, it looks like some unpermitted work was done. That said, this whole mess is 'dated'; except the upper water meter which must have been recently replaced.
I will have a chat with the bldg. owner to have a little attention done to this when I get back from vacation.
Bottom line would be confirm condition of grounding and bonding, install some close-ups, & provide support for the panel. That's about all I can expect, until they have to touch the service.
