Maker's Mark ID Requested

[RobT]

Hi All,

Because this koummya appears to have a European blade, I was of two minds as to where to post my request. I decided on the ethnographic section rather than the European armory because that is where I usually post but, if the moderators feel I would be better served in the European section, it’s their call. Can anyone identify the maker’s mark?
I have provided a close up photo of the mark and, using that photo as a template, have also made a line drawing.
The mark is stamped on the side that would be worn next to the body and consists of a circle divided into quadrants. There is a six pointed star inside each quadrant. There is also a six pointed star at the x and y axis intersection. There also appears to be some sort of decoration on each of the radii but, due to imperfect stamping and/or corrosion, I can’t make any of them out. The edge of the circle has many tiny notches (something like the edge of a dime or quarter). I don’t know if the notches were made as a design feature or whether they were a result of the stamping process. On the other side of the blade, there is a odd patch of corrosion that may have been another maker’s mark but, if so, the pitting has so completely obliterated it that, even under 30X magnification, nothing discernible remains. (It is likely that, had it contained Christian symbolism, it would have been deliberately effaced as politically incorrect,)
The very nice blade is a bit more than 9.5 inches (24.1cm) as measured from the center of the blade at the ferrule to the tip. The rest of the ensemble, although rather old, is unremarkable. The sheath is brass. The hilt is incised wood with a brass ferrule, band and pommel. It would appear that the owner was a man of limited means who put his money into function rather than presentation.

Sincerely,
RobT
