it's a 1925 .375 Flanged Magnum single-shot falling block built on a 1902 Webley action. It came scoped (done after WW2) with a fixed-power 6x42 Zeiss Diatal in claw-mounts. As a rifle, it is a "minor celebrity" for having been described and mentioned by serial number in the book The British Single-Shot Rifle, Volume V. According to the original H&H records, it was made for a gent who was on his way to the Himalayas (perhaps after thar? the mind wonders!).
