I have no interest in the gun, but as you point out others might.

52xxx SN potentially puts it circa 1921 based on data from the “British Gunmakers Vol 1”

Likely 2 1/2 inch chambers.

Original quality of make and condition is everything.

Working mechanics, Extractor v. Ejector, engraving, which patents, all matter.

Preeminent in condition is the barrels, the wall thickness etc. rare is the small gun store with a wall thickness gauge.
