All About Pocket Knives

Has anyone here ever seen anything like this Catt.? Not my knife or pics so I can't really answer any questions about it. I was asked by the owner if I'd ever seen one before, which is a big no. Not even sure if it's all original but it looks like it from what I can make out, although I'm completely stumped by that pattern and Scagel-like blade hole. Definitely looks pretty worn down blade-wise.

Colloquially called a "dogbone" Catt, the handle/ frame are original Catt. The blade is a who knows who made it and installed it in the handle, not original by more than a mile. Fairly rare pattern but correct other than the preposterous blade.

Thanks Gene, I had a feeling that was the case. I have almost zero knowledge in the Cattaraugus department but I've only ever seen a long clip in a frame like that. I'm wondering if that blade might have been made in someone's garage, never seen anything like it.

That's not one of those A.G. Russell Japanese made Catts, is it?

Gene pretty much nailed it. Looks like it probably has a CCC shield.
