Danbooru の英語定義
The "Trapdoor Springfields", named due to their distinctive hinged breechblock that opened like a trap door, are the collective name for a series of weapons created by the Springfield Arsenal from 1865 to 1903. The Model 1873 pattern was the first breech-loading rifle adopted as standard-issue for the United States Military. Due to budget concerns and the overwhelming amount of muzzle-loading muskets filling government storage after the American Civil War, the Arsenal elected to base their weapons on the existing patterns, rather than creating a wholly new design.
