The Meteor chromatic must have come out around 1954, at least that is the time when the patent# 8724 was granted to Helmut Hoyer, Klingenthal. Helmut Hoyer worked for the VEB Klingenthaler Harmonikawerke. The interesting thing about the Meteor chromatic is its curved mouthpiece as well as the assembly of the push button. The button is attached to a lever. The lever pushes against a spring to change the position of the slider and therefore to change keys.
VEB came out with two models. One with a gold the other with red labeling.
Chromatic Harmonica History 
Thank you for this information. I was under the impression (through a seller) that it was circa 1939. 1954 makes much more sense! It’s a cool little harmonica!

Those are need harmonicas. Kind of capturing the spirit of the time.
