During my music life I was an owner ab 20 or more Musima double basses which was maid in former West Germany till 1989.
Now I have 2 Musima basses and the last was buyed by me yesterday for 7000rub -ab 230$

Full carwed solid wood)
And all Musima basses have a serial № stamped at the bottom near endpin.So it could helo to recognize this basses)
