Thankyou all so much for your help. I was able to get onto Cindy, here is Australia, who then put me onto someone else in the US who was able to get me the belt I need. I also found out it was made in Japan, in 1960 to be exact. I have the cams for it, and I managed to downlaod a manual for it as well, so with a bit of luck, Ill be able to get it going very soon!
Thanks again for everthing :-)
