Paul, Morton's have been in touch but so far have not provided any photos of the Earls Court show of 1953. I've had a look on their website but I think its only a fraction of what they have. A good friend and regular contributor to the paper suggested that the finished article will prompt for them t...

Thanks for all the suggestions.

Cheers Rob

Makes sense to be in there Thanks Rob
