Two views of the original valve head.
It appears to have been sprung open at some point, though how and why
remains a mystery.

the cable position suggests it was never put on properly

The clip on the back which is supposed to secure the valve head to the
valve had jumped out of its guides so the valve head was essentially free
floating.

Picture of the boiler front.

It has obviously had the original controls disabled and an external
controller fitted.

The boiler temperature thermostat still works but one built in timer is
missing (HW) and the other (CH) is thankfully not doing anything obvious.

Does have a sticker on the top saying that the CH and HW are now
controlled by a separate controller.

Any guesses how old this beast is?

Front panel says Gloworm 85/100.

1970s most likely, could be 80s.
