All About Pocket Knives

I just received this very nice Robeson from knifeaholic (Steve Pfeiffer). It's a "strawberry bone" delrin stockman.
Stamped on main blade only.
The other blades are not stamped.
ROBESON
633884
USA
Q #1- From the tang stamp and the looks, would this knife have been manufactured between 1965-1971?
Q #2- Was it manufactured by Camillus?
Q #3- The 3rd number is liner/bolster material. 3 is N/S liners and bolsters but this knife has brass liners. So shouldn't it be a 2? Making it a 632884?
Charlie, I would appreciate your help.

Thanks

Yes, most likely made by Camillus after Robeson went out of business in 1965. Still a legitimate "Robeson" as Cutler Federal, who had the knives made by Camillus, did rightfully own the name. They later sold the name to Ontario Knife Company, who still owns it, I assume.

And if the liners are brass, then the pattern number is incorrect or the knife is incorrect, one or the other.

I suspect Camillus did not pay as close attention to those details as Robeson had.

I think I have one of those around here somewhere. I'll check to see if it's the same.
