All About Pocket Knives

I have been trying to find info on this Tested XX knife. Pattern? 4-blade. Cover type?
It was found in an estate, and I have struck out so far.
It's marked: W.R.Case & Sons, Bradford, PA. Tested XX.
Closed knife: 4 1/8" +/-
It's been fun to research the patterns/blades/knives, and learn about Case XX knives and the history.
I have searched (and searched) but haven't seen one like this. "1905-1914" (or counterfeit?) Estimated value?
Thanks, in advance, for any info you can provide.

Sorry to break bad news, but that knife is a fake, a modern made counterfeit.

Like Steve said,fake,and a really bad one.

Thanks for the prompt & helpful info (which happens to be bad news)! Fake!!
And thanks for the laugh, MrBlister.

It's the "high end" fakes that scare me, like a xx era with a shaved tested stamp. a good one at that.

I knew immediately from "outsider" looking in.

The same fact is sure, if I had found that knife I'd sit and ponder, because we are all waiting for that diamond in the rough.

Keep on hunting!

I seen a green bone tested trapper sell for 44 dollars shipped on eBay.

Ive also bought a 70's model 83 with the stamp shaved and the tang "tested", I knew it was fishy. but it was worth the risk at the time.

In hindsight, I should have known it was fake/counterfeit.
1) stamps: "Bradford, P.A." P.A. is not the abbreviation for Pennsylvania
2) shield: Case never made one like that
3) overall construction quality?

I wonder what else I missed.
Thanks again for the info.
