Hi David,
Thanks for the advice. I did a web search and came up with he gentleman's mobile number. I rang but he was busy, so he told me to ring the number you have, and speak to his wife.
Couldn't get hold of her, so left a message - sadly no reply as yet.
I'll try again in a few days, in case they didn't pick up the message.
Good luck with your own research.
Kind regards,
Paulene.
