I thought I would post some pictures of a couple of KA-BAR USMC 1219C2 variations that were hard to find, (for me at least). They are blade marked KA-BAR – USMC and both have a Bonderized, (light grey), blade finish. The top and bottom knife have a thick pommel attached with a rectangular peen. The middle knife has a thick pommel attached with a round peen. The middle knife also has a little different handle groove spacing. All three knives have a thin handle.
The top and bottom knife are the same type as number 11, shown on page 406, in Bill Walters new book. The middle knife is not shown in the book that I can find.
I will make another post on the KA-BAR – USN version of this knife.
