what is this razor, it is some form of flare tip SS but I can't find pictures of the same handle pattern. It is A4 dated, i also have two more that are dated C3. It appears that all three have lost the plating on the handle, except the knob, and it is aluminum under the plating (like i said appears that way). Two of the work fine and one works but when you twist to the most open position if you keep twisting the head twists free of the handle but it still closes tight. I am probably going to sacrifice that one to my engineer's curiosity of how things work and strip it down.
