The 301 would best be called a Cami. special order, without going into records, I believe it is a SMKWs special order. Not actually stocked by Buck. I.E. Note the rivets holding on the scales. The 309 and 305 are mid-80s. But were the first 300 stag scale run and were actually made by Buck in their factory. They just don't have the BUCK shield of the era....The late 80s era had lots of different scale materials available. But such is not a common event in these times......Like you I will state with confidence that the Peanut is bigger than the 305 Lancer and if it beats the 309 in length it won't be by much......I have a Old Timer Peanut around here somewhere.........300
