Heres a photo of the lighting console that we have in the foyer of our old warehouse.
Its a Strand CD 72. It used to run the Princess theatre in Melbourne Australia.
Apparently ( I have been told) it was one of the first memory consoles manufactured in the '50's and it run a mechanical dimmer system that we have only just sold to someone to restore.
I can email some higher res shots if anyone is interested.
