Re: The knives posted previously in posts 16,17,18,19 and 20.
All of the knives shown, were not production knives. Maybe Proto make up knives.
All were made after 1973 in the mid 1970's [about the time Camillus was making the Buck 301s]
#19. "The one bladed 885UH" looks to be a Line-locker.
After looking at post #77 and looking at the 77UH, the knife in post #19 is a 77UH frame fitted with an 885UH blade.
#20. The "S.C.C. 866UH" looks like the Proto for the "S.C.C. 886UH"knife, made by Camillus and sold only through a large Chain Store.
Some very collectable knives... Ken
