Italian or fake (hungarian)

[Gunter Grass]

dear folks,

somebody offered me another bass. the seller told me that this is an old italian or english bass. again, i am not sure if this is a fake. very hard to tell!
to me it definetly looks old, but the back of the bass looks a little strange?
i would be thankfull for any ideas or identification-marks! my eyes are not experienced enough to really tell.

thank you in advance!
