Thanks, Mr P.

It's a bit worn and used with a fair amount of pitting on the blades. I just got some magnification on the tang and the pattern no. stamp is completely missing.
The blades sure look like they were heavily buffed at some time in its life and the tang at the back of the main blade looks to have been ground down a fair amount?
The Cattaraugus Little Valley stamps on the front of all three blades are still legible.
I feel lucky to have found it though, I drool every time I see a pic of yours. The bone, shield, pattern and sleeveboard shape were more than I could resist.
