Not sure about the dot either. The best source I have on that mark says that after 1950, it was changed to a circle divided into 3 sections. However, I have a Webley & Scott 700, 1969-70 vintage, which still carries the old mark like yours.
What other proofmarks does your gun have? If yours has the proofmarks from 1925-54 (shot charge and chamber length) and if that's a B in the left quadrant (I can't tell from the photo if it's a B or an R), then it should be 1951. But if your gun has the pre-1925 proofmarks (shot charge marked but not the chamber length), then it would be 1922-23.
