For your consideration, we have a Southern Pacific Shot-Glass Set. This set is from WWII and in a shell style, made from brass.
This set comes with a total of 6 shot glasses altogether, made from brass shells. Each of them feature Japanese kana on the bottom of the glass. The inscription on the faceplate indicates that these glasses were made from shells from the Southern Pacific theater of the war from Sept. 1944. Under the assumption that the shells are dated to Sept. 1944. It could also be that the glasses were evidently made in Sept. 1944. Although it is more likely that they were collected from this date presumably by a U.S. service member. Hence, eventually made into shot glasses later on, either as memorabilia or to sell.
Each shell has Japanese kana stamped on the bottom, not complete markings with dates, numbers and so on. The kana are シ (shi) and ム (mu) in katakana. Although we are not especially sure on what the meaning of the markings from the time could be. We assume the presence of kana indicate that these were indeed shells used by the Japanese during the conflict originally. Evidently, that is simply a presumption. Every shot glass measures 34mm in diameter with a 29mm diameter base and 51mm tall. The glasses and box are in okay condition, no major damage or dents, mainly just dirty from being in storage for a long time and need to be cleaned/restored.
This Southern Pacific Shot-Glass Set is a perfect classic addition to any collection!
