I'm replying off-list to everyone who responded to my PLESTER enquiry - but I still have a couple to write to, as so many took the time to write to me. I poster the enquiry to seven Lists and was, to say the least, amazed by the number of responses I received and by the lengths some people went to, to gather information for me. So a very big thank you to everyone. John ONS: www.plester.info
