Thanks mate.
Yeah, I'm a member of MoPo.
Only contributed a few times - never emailed someone on it.
I'll try now.
I'll let you know what transpires!
EDIT - I don't have Microsoft Outlook enabled, so can't email him.
Thanks again!
This is why I still think this forum should start a link exchange because if it wasn't for you being a member here I would never have got closer to a "definitive" value as such.
Best,
