its a re-fin, and i doubt some of the originality of it.
the bridge is vintage but......
perhaps a later pieces with newer sandles.
its much too shiny.
same thing with the guard, looks too nice to be a shrunken tort guard.
at that price and condition i would want to take the whole thing apart and inspect every inch of it,
but besides that the neck is rare as hell by it self, i think i have seen 2 other block n bound lefty jags
