Camillus Sunfish Elephant Toe Knife Bone Handle Long Pull For Sale

Recently I purchased some items from a private estate - Included were some knives - I know very little about them so bear with me on the description. If you need more information please let me know. For your consideration is this great looking "Elephant Toe" knife from Camillus Cutlery - Camillus NY - USA
From what I have been able to determine this was a large knife used by construction and oil field workers and dates back to the early 1940s. Overall length is a about 4 1/8" and it is a wide knife 1 1/2" (when closed) There is some minor pitting on the blades that does not show up in photos. Also some scratches. Blades are super tight. It is very sharp as my thumb now knows - cannot tell if it has ever been sharpened before. Both blades have Camillus Cutlery on them. On the big blade there appears to be a very faint engraving that may say "Gentle Giant" and it looks to be part of the blade and not added.
