Welcome to the forum!
Make sure to search both this as well as the old forum (
http://www.vikingsword.com/vb/forumdisplay.php?f=6) for interesting threads! There are a few folks here with extensive knowledge on Koummyas - I'd like to hear more often of these nice bades though!
I assume you've already seen this article

This seems to be a nice piece! Could you please measure the thickness of your blade with calipers? This helps to differentiate serious blades from more decorative/ceremonial ones. Recent tourist stuff is often more easily spotted by crappy blades (which actually don't deserve to be called blades); older tourist stuff can be anything in between AFAIK...
Do you have another example of this stamped mark? More often these seem to originate from stamped European blades which seem to have been prized by Moroccan makers.

Kai
