SHASHKA for Comment and ID

[kahnjar1]

I recently picked up this Shashka which I think is Caucasian. This earlier thread http://www.vikingsword.com/vb/showth...hlight=shashka ,attempts to identify where the particular styles come from.
Referring to the feature ID shown at Post#71 of this thread, it would appear that mine is Caucasian BUT it has features which do not tie in with that given.
Suspension is blade edge DOWN rather than up and of course with the silver covered hilt, it is not possible to see how many rivets are present.
There are no markings on the blade BUT the letters A.C. are stamped into the hilt as shown.
Any information as to origin, and any comments are very welcome.
