Here's an evolution of design change by Manufrance over the years both in 16 ga. The left one appears that it required more machining than the more modern design on the right. The earlier design was from the late 1800s until some time in the 20th Century and both overlapped in later catalogs. The chrome plated part on which slides the shell holder is trapezoidal in cross section and if slightly bent makes closure more difficult. The newer version appears to be less complicated in design and manufacture. In discussing with someone more knowledgeable than I about the manufacture of reloading tools, I commented that it appeared that MF was the only manufacturer that made both tools and guns. I was corrected and told that Winchester made some for the American market which were sold under different brands. Gil
