My thread title is my question. The R1263 is the approximately 5 3/8" banana trapper pattern assembled with clip point master and pen blades. I have the 3 variations that I have seen, a 1986 R1263 Hunter with brown Delrin sides, a .257 Roberts Camillus Classic Cartridge CCC-4, and the 1998 National Knife Collector's Association (NKCA). The latter two have the same jigged bone as Remington sterling Silver Bullet knives. The NKCA knife has a NKCA shield on the marker side and a Camillus shield on the pile side. Since my NKCA knife's pen blade is stamped CCC-4 it appears Camillus used up left over CCC-4 parts in NKCA knives. Apparently this was not a popular choice of blades in banana trappers so my guess is the reason I have not seen a sterling silver bullet R1263 is they sold poorly. If any were made I'd like to complete my collection.
The master blade in these matches my most used kitchen paring knives closer than any other pocket knife and while camping I use knives for food preparation more often than any other use.
