The 'C' w/ the Broadarrow on the butt is the Canadian Property marking.
Thos markings on the left side of the bbl & frame ring are the Birmingham Proof Hs proof markings that go along with the Birmingham Nitro Proof mark on the cylinder.
The Bbl markings are 1954/55 and on forward.
They give :
The caliber of course.
The case length (only) in inches.
The Service Pressure in English Tonnes/ sq-inch
Crown/BNP is Birmingham Proof Hs Nitro Proof.
Kind of interesting that the Proof markings are not inside Circles.
That is what was specified in Proof Law for firearms that were not of English mfg'r, and the guns proofing (or lack or it) in it's original country of mfg'r was not recognized in England.
Before 1954/55,,that point was simply made by stamping the firearm with a mark that said 'Not English Make'
Maybe the Circle stamps weren't close at hand that day at the Ol' Proof House!
"...Assuming the barrel markings point to a Belgian Mfr barrel?..."
Perhaps since the conversions were done in such large numbers, the bbl relining work was shuffled off to Belgium/Liege. The completed bbl proofed there before returning them to England.
When the completely assembled conversions were done they would have had to be proofed in England before going out on the commercial market. Even if they were destined for the surplus market in the USA.
Nice revolver..
