Mystery of the fourth tie - SOLVED......?

I had a very exciting email form one of my clients this week relating to the Rocha John Rocha tie, one of which had been sold at the Feb 2010 Bonhams Doctor Who auction.

The sale of the tie, along with three others, had been the part inspiration for my Tie Index, and when I was compiling it I fully expected all the ties to surface at some point. I was suprised the to have one left over - the Rocha John Rocha tie.

Having established it's non-show on screen, I did keep an eye open in case a supporting actor had worn it and it had been wrongly attributed for the auction. Still no luck there.

It was looking like the Mystery of the Fourth Tie would never be solved . . .

Anyway, so now the new lead.
