Mal, is there any dating possible with the barrel tube numbers?

This is certainly not a Beesley (Purdey) patent action gun. I'm not positive what the lock pin placement tells us other than that it is not a Beesley or Royal action, and, I don't think a Grant or a Woodward action. I contend that the "fern chisled fences" are common on many brands of guns. Does anyone disagree with that?

I'm also under the impression that Mr. Beesley saved his best work for the Beesley patent self-opening action. I'll continue the research further.

Nice discussion!!
