John, almost certainly not a F Beesley gun. I have never seen a Beesley with disc set strikers or side clips before.
Furthermore, he was a man who would have had no fear of putting his name to a gun he had made.
Lastly, he actually made very, very few guns on his Patent 31 system after he had sold it to James Purdey.

It was just a thought! It looks to me to be very well made, and of course that action is not an easy one to make. I know a considerable number of people have made it in small numbers, but can't think of having seen an un-named one anywhere before.
I'm not a great 'proof marks' changes expert (or expert at all for that matter!), but the 13/1 with no chamber length specified and the fact that it is black powder only presumably makes it very early and so probably in the years of the patent being operative - and yet there is no 'use number' that I can see - which I would have though should appear?
I'm also not familiar with that way of retaining the extractor/ejector legs, which again looks well executed.
