Identifying long thin spoon stamped 22

[StumptownJoe]

• Stamped 22
• Stamped with a diamond-shaped mark that I can’t quite make out
• Engraved “HM” on the bottom-end of the handle

Thanks for your help in identifying!

Although I can’t see the marks in the spoon to tell you more, their placement is typical for French silver. You might look through French silver marks here.
