... This one looks like it has a stradella bass...

Though that slanting alignment of the bass buttons would be typical of diatonic basses made for some (especially central- and eastern-European) markets.
Kind of an unfortunate name really.
Oh I don't know - Gibson have done more than ok with its English counterpart "Mastertone"...
"Meisterklang" was a brand name of accordeons produced by the Ludwig brothers (Gebr. Ludwig) in Zwota (Eastern Germany)
Might be 1950s or 1960s.
Yes, and here is definitive proof that Ludwig used the brand (though it's the
k and the
l that are damaged on this one's name badge, rather than the
g):
And, judging by instruments I've seen, they seem to have started to use the
Meisterklang brand as early as the late 1930s.
Not a million miles from Klingenthal ...
Indeed not, in fact (having walked there) I can confidently say it's "just down the road" from the Weltmeister factory...
Zwota is one of the villages that make up the elongated town of Klingenthal.
