Up for sale is an original World War I U.S. Army Model 1910 Metal Marking Outfit box containing 36 of its authentic military steel letter and number punches. This historic piece features an incredibly rare, pristine factory instructional sample paper label glued inside the lid that has remarkably survived fully legible and oil-free for over a century—a detail that adds tremendous value and makes it an elite display piece for serious militaria collectors. The solid wooden chest and its original brass latch hardware are completely structural and intact. Mechanically, the kit is numerically complete with all 0–9 number stamps and is missing only a single letter punch—the letter "R"—making it a perfect donor set to complete another kit or a fantastic standalone relic. Please note that this listing includes only the wooden chest block and the 36 steel punches shown; the original heavy steel anvil block, the alignment guides, and the brass mallet are missing from the set.
