Notes: : * I recently bought an XX75 collection which contained several different 1970's bone models and exactly 12 1970 10 dot stag models. Although the seller didn't say, I am certain these were originally purchased as a dozen box. They are all exactly the same condition, burn level, and assembly character. These seem to have sit in a box for 50 years together. Edges still have original burr, and all have only a spot or two (specifics for this knife below).

* Some tiny spots on blade / backspring
