Bass id?

[Hannes Beyer]

Hi everybody and thanks for letting me be a member of this great forum!

I would like to know more about one of my double basses and hope to get some help here!

The measures are: string mensure- 42.7
Back including button-44,4
Upper bout- 19,9
C-bout- 13,8
Lower bout- 26,1
Ribs at c-bout- 7,2 and 5,3 at the neck.

I really don't know anything about the bass, but my best guess is that it's a German factory made bass so I'm posting this here!

Best regards, Hannes
