In 2001 Gerber honored the introduction of the first run of Mark II knives ( 1966) with a limited run of only 1,250 – 35th Anniversary Series knifes.. This special run was made to the exact specifications and design of those historic knives first made in 1966, most of which were ordered and sent to US Military Troops. This knife is #010323. It has never been removed from the box and remains in Mint condition. The Gerber Mark II was one of Gerber’s premier products and the older knives are still in high demand. The Anniversary series were designed, crafted and made to the exact specifications as the older knives were made, they do not represent the design of Gerber’s newer line of Mark II knives which were introduced a few year ago. This knife is properly marked 35th Anniversary 1966 – 2001 along with the appropriate serial number. A true collectors item. This is the last one I have for sale!
