C,
I do not have numbers produced on record. But, either Scharde made or Camillus made early black sawcut models with no model number on reverse tang seem the hardest to find. Especially in the Schrade. That would go for either 301 or 303.
If there were a 303 elk antler scale LE dated in 1988( made by Buck), I might jump over a yard sale table and wrestle a concrete worker for it. (Maybe two, but not three)
I have 301s LE but have only one 303 and it looks like it has one side replaced with regular stag...Salesman sample ?. Also a pre 1985, Camillus, in regular stag scale.....lots of folks don't like elk because it is less ridged than stag but everyone to their own......
It looks as if the early stag LE will have two SS scale rivet and hidden spring rivet and the Elk LE will have only the brass spring rivet showing.
Elk, some elk ages with time and oil to a green/yellow color I like but most don't. Some say it is more prone to crack than stag.
Stag, LE
