Atlas Super slim & T12 Thorn Pop packs still in use

These are still in use in a local glaziers workshop where I was waiting for some glass to be cut to size. I think this place has been here since before I moved to the area back in 1978. Some of the fittings had been replaced with unknown twins over the bench where they cut the glass, I would guess that they decided that they needed more light. There is also a floor standing Glowworm boiler that looked to be from the 70s for the heating.
