This was a gift from a former employee of mine-( I do wish people would stop giving me knives-LOL). Anyhow, this is a Kinfolks stag handled Flame Edged Super Hunter-model 568 TC with a carbon tungsten edge on the blade. The question is, I have seen these dated from the 1920-30's all the way up past 1957 when Robeson acquired them.Since that is a span of 30-40 years I would appreciate any help in narrowing down the date  on this knife-Thanks in advance-
