I also have a cymbal marked "Metior made in w germany" with a star, it is the only mark on the bottom side of a pair of hi-hats that are clearly older... I could perhaps capture a photo of the mark, but a simple internet search yeilds nothing.
This came with a blue sparkle no badge kit, the only other cymbal with the kit is a 20 inch zildjian with a 1 1/2 inch stamp that looks by its condition to be from the 70's, but I have no way of knowing if this gear originally came together, again, I would be happy to submit photos.
I bought the kit dirt cheap for parts to complete a 60's Star kit I have recently acquired, but will now be building a hybrid kit from the two, sort of a monster kit a la early Hal Blaine.
I would love some help nailing down the years these cymbals were produced, other than the obvious clue that W germany existed for a very narrow number of decades. Thanks for all your help~
