Your thoughts about this bass

[Bob Van Basten]

Hello,

Does anyone have any comments this bass?
The label states "Johann Radeck Bürger", the seller says it's Austrian and he bought it from a Hungarian musician. Asking price is 3200$

Any thoughts about the structural quality, guessed value, age, ... are welcome.

Any ideas why there is a horizontal seam on the back?

Thx in advance!
