John,
That would be from Green’s last shop near the Restoration Inn. Dudley Green moved about 3 times as Cheltenham High Street was re-developed.
I wish that I could remember more about his shop as I saw it in the 1950’s. The one thing that has stuck in my mind is that on display in his shop window was a Borchardt pistol with a clip of cartridges.
I think it was displayed as a curiosity rather than just a slow seller, although I did buy at his last shop a small Dixon pistol powder flask that appeared brand new.
