All About Pocket Knives

I have collected knives for many years but I'm far from what one would call a pro on them. My choice of knives to collect is case xx. I picked this knife up along with several others at an auction. I have never seen one with the markings on every blade or the bolsters pinned on a whittler like this one. Can any of you knife gurus please confirm if it's a fake or not. The knife is very solid, very strong snap. Blades have clearly been buffed. Model 6346.
Thank you very much

Not an old Case factory knife.

I figured as much, thank you for confirming.

I think this knife was made from one of the Winchester reproduction knives
