Hello Ariel and Charles,
Thank you both for your comments!
Yes, the ganja isn't separate, this is clearly visible but not separate ganjas I've seen by examples from around the second quarter of the 20th century.
My own age guess was post WWII until the 70s last century which would mean that it is a vintage piece and I am happy with this age guess.
Like said before, long already I look for a complete example with these MOP plates at the scabbard and handle. Who have watched the market will know how seldom a complete example appears.
Of course it would have been nice to have an older blade refitted in such a dress but it's ok for me as specimen copy.
And the price was right.
Regards,
Detlef
