BenVA,
The original 111 with engraved aluminum frame was actually made for several years. I will need to check my binders to be sure, but my memory (often faulty at this point in my life!) says it was issued in mid-1981 and remained in the Buck catalog for about three years. I know they were available in both 3-dot and 4-dot versions.
Of course, two new 111s (one a bareheaded elk handled knife and the other with nickel silver bolsters and ironwood inlays) are based upon the famous 110 and featured in the 2005 catalog. We are awaiting actual production and shipment on these two models.
I will try to check my mid-1980s catalogs. If anybody else can give a definitive answer, feel free to jump in!!
