Dear Les B and Keith,
thank you; as you can imagine I was somewhat dumbstruck when it popped up in front of me. I have Robert Hall's book so have been well armed with experience of what one looks like. Though this is the first I have held.
Keith,
if Mrs K wants one I notice Selmans in the USA have/had one up for sale in their recent auction. :-)
Kind regards to you both.
Andrew
