The box that you can barely see- between the meter and the open coupling, just a bit higher- is a 4-square box with an ordinary blank cover.
As best as I can tell, the original panel was in the large box under the meter. There are numerous pipes that exit this box that you cannot see, as the entire wall has had an inch of plaster / stucco applied over the brick base. That 4-sq was there before the plaster was applied.
For some unknown reason, in the murky past, this panel was gutted, and a new panel installed next to it. This is the panel with all the crappy pipe coming from it. The "new" panel, btw, is a Zinsco. The original panel is nothing but a junction box now.
You can see a number of pipes added to this new box. Almost without exception, these pipes were run completely without support. There is also, in these runs, what seems to be an avoidance of the use of LB's, proper offsets, or holes drilled.
So, I rather suspect that much of this was done by some handy sort, who had never used a bender before, and had no idea as to the materials available. This being a transient motel, said person was likely without a car, and had to make do with whatever the manager felt like providing.
