Thanks CyberJack for all your help.
I'll PM Deejay and Bonnar Bloke and see, if they have time they might be able to shed some more light on it.
If anyone else knows anything else please don't hesitate to post something!
Indeed it does not detract from the fact that it is a rare machine. The information you have provided is invaluable!
You are a champion CyberJack thanks once again!
