I came across this last week during a trip to Teguise, Lanzarote. Is anyone familiar with the make and model? Those look to be 6000ft reel boxes.

The plate on it says "Supersond. S A", this was a Spanish company. The spool boxes do not colour match and are obviously 6000ft.

Thanks Maurice. What I wondered is where the soundbox was.

Well, the exciter lamp is to the left, therefore the PEC must be in the fitment behind the red logo with hidden wiring to the mech and thence to a pre-amp. The end of the sound drum no doubt extends into the mech to its flywheel.
It looks a right cock-up and certainly seems like an original silent projector which has been badly converted to sound.

Ah yes, I never even noticed the exciter lamp there. Yes, it looks very strange.
