Dating usmc us dog tags
I checked fold3 and and didn't find a match to your John A Janson though.The imprint, excluding the USMC, is consitent with other WWI dog tags. There are several John A Janson's who registered, however cross referencing them against the 1930 census shows that none were veterans. It's a 1917 Connecticut Military Census completeted by John Janson, dated February 23rd, 1917.
General Order Number 10 of the 6th Regiment of Marines dated 15 February 1918 specifically stated, "The numbers assigned to all men present will be stamped in identification tags." There was some clarification in General Order Number 91, paragraph II, of 10 June 1918, which read as follows: The aluminum identification tags, each the size of a silver half dollar and of suitable thickness, will be worn by each officer and soldier of the American Expeditionary Force and by all civilians attached thereto. F., in 1917, will be issued until the present supply is exhausted.I checked fold3 and and didn't find a match to your John A Janson though. The USMC didn't start issuing service numbers until 1920, same as the Navy.So it could be a US Army tag with the USMC engraved later.The tags are prescribed as part of the uniform and when not worn as directed, they are habitually kept in the owner's possession.When they are not worn, the identification tags are considered part of the individual's equipment and they are are inspected regularly.
