Frame and Main Handle Changes from Type J to Type I

Here the slim-waisted handle of the Type I (at left) was made more robust in shape with the Type J(at right) as was its connection to the frame also beefed up from the Type J to the Type I. Note that the handle was not fundamentally changed except to truncate it to fit the larger diameter brass ferrule. It was the brass of the nickel-plated ferrule that was the real source of weakness of the No.2's main handles. Because the brass had not been stress relieved, it was prone to season cracking when exposed to certain agents such as ammonia. When the ferrule broke, the handle could not resist splitting and quickly loosened.
