I am looking for manuals and, if possible, schematics for the original strand environ dimmers also known as the Strand Environ 1 or Environ Multidim.

They were architectural dimmers produced by Strand in the late eighties/early nineties that attached to a bespoke baseplate that contained terminals for fixed mains and control wiring.

Documentation for these seems to be as rare as hen's teeth but if anyone happens to have any or can point me in the direction of someone that does it would be greatly appreciated
