As a matter of interest, Paul, John Rogers was also at the summer gathering yesterday and he had similar looking items which did not sell! He is on this forum as 'L2Magna' and may be able to assist you.
Hi Paul, I'll send the middle one off to you free. Should only be a couple quid no problem, especially if it helps. Do let me have your address offline and I'll get it sent today ... another one will appear I'm sure. best
