That was my Mod. 11 with the riveted sheath. I wasn't crazy about the 11....I didn't like the brass on brass. I bought it for the sheath. That was one of the neatest sheaths ever! One day last year Joe called me about the knife....wanting to buy it. I asked, "how the heck did you know I had it?" I think Joe and Mitchell have a sixth sense about these things. They turn up some dandies. At any rate I let Joe talk me out of it.
