All About Pocket Knives

I’m new trying to discover info on my knives[image][/i

Hi and to AAPK. I'm pretty sure that is a 67, not an 87 pattern number.
Called a Stockman style. Maybe from the mid to late 1950's, possibly later. Long line tang stamp.
I'll guess Delrin handles. They are a popular and a pretty common type of Camillus pocket knife.
Below is one of my 67's.

That is definitely a 67 pattern stockman. I think that tang stamp was used somewhere in the 1970's and 1980's. Good knife, I have one just like it.

Given the handles (Delrin® "Indian Stag" jig) are attached by post instead of pinned, combined with that tang stamp the knife was probably made post 1976 to sometime in the early '80s.

Ignore the prong attachment picture. That's for synthetic (plastic) handles pre-mid 50s and earlier.
