Thanks for that, Jojo. Orla McCartney from Diageo has contacted me directly & we are now considering putting it in the next whisky auction with Bonhams in Edinburgh.

We live in Kent UK & are - coincidentally - visiting family in Inverness in a few weeks time. As our route takes us via the Edinburgh ring road anyway, it would appear to make sense for us to drop the bottle off at the auctioneers on our way north, so things seem to be working out quite nicely. Almost like it was just meant to happen

Thanks again for your help.
