WWI Marking Outfit

Q: I recently bought this wooden case, which is 8 inches long, 4 inches wide, and 3 inches high. The letters on top say "Marking outfit for stamping metal." Inside there's a paper sticker that says "William Feversham, 1st Sarg't, Co. C, 74th Inf., U.S.A." The tools inside the case include a solid brass stamping block with a brass thumbscrew and four cutout areas marked "spoon-fork," "knife," "tag," and "meat can." There are also three metal patterns stamped with the same words. The other tools include a hammer, a miniature screwdriver, and small stamps that include the letters of the alphabet and 10 numerals. Can you tell me what this was used for and how I can research Feversham's military history?
