Queen Cutlery had the factory in Titusville, PA and marketed scissors, hunting, fishing, kitchen
and pocket knives to hardware stores and other retailers.
this 1960 Queen Steel catalog may help:
http://www.queencutlery.com/uploads/...94_-_1960_.pdf
if you were hanging around hardware stores in the 60's (like myself) their display is familiar.
you might make note of the often referenced "special steel formula" and "secret tempering process"
your knife is on page 15
as you can see on page 52 the #2 pocket knife wholesaled at $19.80 per dozen.
they seem to be collectible these days
hope this helps
