William Watson & Son, makers of the No. 32 Mk I and II scopes were badly damaged during the Blitz by German bombers, thus their contract for Mk I scopes were delayed until repairs were made. This is why there is 1943 and 1944 dated Mk I scope's in the 14,000 range; they were contracted to make Mk I scopes so they did, even though the Mk III scope was soon to be made at other companies. You are fortunate to have a matching example with rifle, I have been searching for an example to add to my collection for a long time. If possible can you post pic's of the rifle, I would love to know the s/n range of the '44 BSA it is paired with.
