Thank you for your response, Jim and thanky for the link. Will request to get the pdf from the author.
I like to see differences in the pommel holes fitting the tang (tight fitting vs. asymmetrical wide hole). My ressources are two own images and one I found in an paper online:

Interestingly here the author assumes that in this case the pommel could be mass production and the wide hole later been fitted for the certain blade / tang.
