Manufactured in 1910 with several special features like a three quarter magazine and shotgun buttplate. The receiver lacks provisions for a saddle ring. The barrel is fitted with pinned blade front and three-leaf rear sights and is marked with the two-line address/patent dates and "38-55" on the left side. A Winchester factory oval proof is stamped on the barrel and frame. The upper tang has the three-line model/trade mark information. Mounted on a smooth straight grip stock fitted with a factory hard rubber shotgun buttplate. Special length magazines on carbines are even rarer than those found on rifles.
