A solid hallmarked silver mess knife belonging to RSM James Ranken 42nd Royal Highlanders, c1847.

According to the Succession of Sergeant Majors 42nd Highlanders, James Ranken was appointed RSM 22 June 1847.
He was discharged to pension 10 November, 1853.
Then Quarter-master Argyll Militia 14 April 1869.
Beautiful condition with a lovely patina.
Clear Scottish hallmarks which I am hoping somebody can decipher.

This item is outside my collecting field and would be happy to exchange for a SBP or similar.
