Old...antique...and beautiful!  Authentic pocket knife with great patina.  My guess is that this is from the very early 1900's.  Its maker is a mystery as I cant read all of its tang stamp.  My guess would be Challenge Cutlery Co., Baldwin, or maybe PAL.  I can see "USA" and "ry co."
 
No chips in either scale.  All blades open and close.  Snap on the puch blade...no snap on the other two.  Some signs of age on blades.  SEE PICTURES.
 
3 1/4" long when closed.
 
THIS COULD BE WORTH MUCH MORE THAN I AM ASKING DEPENDING ON THE MAKER.
