It's the Vedo Villi of 1911.
After that last clue I can't claim much credit though, it just happened to coincide with my coffee break.
That thread did occur to me , but I didn't check it out as I knew that Graeme had posted to it and he seemed non-plussed too.
Open House when LM confirms please, as I'm back to work now. 'Twas a good Challenge though!
