Interesting, thanks. To my eye though, the
MOB 9306 pliers look identical to the
Dolex BC220 pliers, except for slightly different rivets.
Otherwise, the shapes of the upper and lower handles seem to be the same, the rivet locations are all the same, the pin style in the 4-step adjustment mechanism is the same, etc. There is a tiny gap between curved edges of the upper and lower handles near the mouth of the pliers in the MOB that doesn't appear in the Dolex, but it's slight enough that it could just be the difference in camera angles, where the Dolex picture doesn't show it.
Contrast that with the SAM pliers, in which both the top and bottom handles have very different shapes than the MOB/Dolex, especially where they come together near the mouth of the pliers, as well as having very different styles of rivets as well as a different type of pin in the adjustment mechanism.
Of course these could all just be attributed to different revisions of the design, or options in the manufacturing. But it seems like the SAM pliers have as much chance of being supplied by Dolex as they do MOB, especially since Dolex is also French like SAM. Maybe the MOB pliers are also made by Dolex?
