Hi Rick,
thank you for fast respond.
I am very unsure, it is obviously an old blade with an old gonjo repair and an old worn pesi. I have taken some close ups now where you can see (I hope) why I am a little bit distrustful. Look at the first and fourth picture! And I never have seen before a blade with such a shape/dhapur. I have learned here and by years of collecting to be suspicious.
Regards,
Detlef
