Original Pulsar/Rigel Shutter System - Information?

[pmlogg]

I think I asked once before but does anyone have information about the Pulsar/Rigel motorised shutter system for the original type of Pulsar 2.7m dome, i.e. with the two-part shutter?  I did ask Pulsar but they couldn't help.

All I have been able to find is an advertising image of the control box.  Images or a copy of the original fitting instructions would be great. 

P.S. The Parvalux gearmotor in my original type of Rigel rotation system has packed in.  I've seen images of the Rigel system that came next, but still fitted the original type of 2.2m dome. It seems to have used a different motor, mounted vertically rather than the Parvalux with a 90 degree downwards gearbox output.  Any information on that other type of motor and how it was mounted would be much appreciated too.
