"Hello, since the Polish hallmarking law of 1920 the word "Metal"(since 1932 it was just "Met", later it became "Metal" again) was used on pieces that combined precious and non precious metals. It was to tell the buyer what to expect. So it wasn't jus a word, it described a quality of the object this was stamped on. Best wishes, Banner."
This is just a guess, but would the phrase "Met-Div" mean "Diverse Metals" in other words, two different types of metals are used in this object, which is partially made of 935 silver and partially made of base (non-precious) metals?
I am unclear on the makers mark, but this would direct us in the direction of Poland, at this point, if this is takes us on an error journey I cannot know...
