Identify a Case pocket knife

Hello, I am looking for help with a Case knife that I have.  Here is what I do know about the knife,  it is 6 1/2” unfolded and the single blade is 3”.  The stamp on the tang says W.R. CASE & SONS BRADFORD PA. I know from this stamp it was made between 1905-1914.  Any other information would be greatly appreciated.  Thank you
