These are photos from a domestic installation in the UK.
Probably dates from the 1960/1970s.
All of the items are in working order and still in daily use.

40a_ferranti_meter - closeup of the all-mechanical electricity meter. Rated 40A , 240 volts. From here, a mineral insulated cable (mims/micc) goes to the 2nd floor to a metal Wylex panel.
wylex_metalclad - outer view. The original rewireable fuses have been replaced with plug-in circuit breakers, probably around 20 years ago. The whole unit is recessed into the wall, the routing of the cables is unknown:
wylex_open - interior view. Most of the property is wired in MICC. The black box above is a doorbell transformer. Earthing is provided via the metal sheathing of the cables, so no earth wires here. The large green/yellow wires are equipotential bonding to the gas/water services, this looks to have been added very recently (plastic mini-trunking at bottom right).
The breakers are rated 30A (red), 15A (blue) and 5A (white). These allegedly supply cooker, socket outlets, water heater, lighting and another set of lighting - but someone has made various modifications since the original install, and some of the lights are now powered from the 2nd 30A breaker. You can see from these ratings that the 40A meter downstairs is grossly undersized, even allowing for diversity:
freidland_tx - the doorbell transformer. Not connected, the circuit breaker has been removed, so probably defective:
mem_singleswitch, mem_dualswitch Light switches, single and dual gang:
