Mystery solved.....Jeff has written from Australia..
The mystery has been solved. Sandy Henderson replied to an email enquiry, confirming that the bowl had been made by Ian Jones. Sandy replied as follows - " Greetings from Inverness Jeff, The subject bowl was turned by a good friend and fellow woodturner of mine, Ian Jones, who for many years stayed and turned in Landbryde near Elgin in Scotland. Ian left Scotland some 5-6 years ago and now stays in Cambridge, England. He no longer turns but we keep in touch with each other. I shall be only too happy to inform him where his bowl has turned up (excuse the pun) !
Trust this will be of some use to you and the family who now own it. I hope they treasure it, not only because you have made a lovely job of refurbishing it, but Burr Elm is now as scarce as hen's teeth and very costly ! Your as aye, Sandy"
