Thank you to all,(so far) who have replied on this thread,
Philip, thank you for all your technical support. I have never been lucky enough to own a GS1200 or any of the Beaulieu projectors. I did see a particular company charging a few hundred pounds for a new rubber roller. This was enough to put me off buying one. They certainly look the business, and like many machines, i know these also have there problems.
Therefore, anyone who produces spares is to be commended.
