Howdy - got directed over here from KFC, and I think it was good advice *s*. I have an old 110 acquired new circa late 60's. It has inverted BUCK USA on the blade & the sheath is stamped 110 on the belt loop. It has only one pin through the wood inserts on the handle. What "generation" is this thing, and when did Buck start manufacturing the 110? I bought this one while a cadet at USAFA before I graduated in '68. What would approximate value be - its well used and often sharpened, but clean, no dings or scratches on blade or bolsters.
