Jerome Thibouville Lamy Bass?

[Nelson Cascais]

Hi

I´m interested on buying this bass and I would like to know if it´s really a Lamy and the estimated value on the market.
The seller says that it´s a Lamy circa 1880.
And how about this bass maker? I know Bernardel, Vuillame and Jaquet but
I don´t know anything about Lamy.
I didn´t try it yet cause I´d have to travel so I want to know more about it before.
I play jazz.
The seller is asking 9000€, 13400 USD aprox.

Thanks!

Regards
Nelson
