I believe this is a "put-together" outfit. The knife appears to be too early for that sheath. There are no model #'s on the "C" styled sheaths anymore as they share usage with several models. The #15, #17 and #18-5 1/2" all reside in the same leather. Hope this helps...(or not)...
Best, Capt. Chris
