Mathias Neuner bass, worth it?

[Frank Larouche]

Hello everyone and hello Ken,

This bass appear today in the kijiji ads in my town and from the pics I'm not sure what it is, in the description he say it's the original label by Mathias Neuner, but it's roundback and from what I've checked so far bass from this maker tend to be flatback but I may be mistaken. I look like a german shop bass too I think. anyway what can you tell from the pics and do you think it's worth 12 k. I will try it of course in the future!
