Hi Yes,
Like Ian I like the blade and the hilt but frankly I wouldn't be happy with the new scabbard, 19th century or older scabbards show a different form and other carvings.
I personally would prefer a scabbard like my antique one in the pictures.
And I am sure that you can find here in old threads other antique samples you could show your carver. And I would advise him to finish the flat areas better.
Sorry, that's my impression when I look to the pictures.
Regards,
Detlef
