Stuart,
Sorry for the delay. I have scanned 3 pages of A4 (as jpeg files) info that might help you. I tried attaching them to a post yesterday (on the practice area) and failed. If you email me directly, I will send them to you. I have scanned each one twice, once as a 50K (ish) and once as a 500K (ish) file. let me know which size you prefer.
Regards
