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 its tang stamp.  My guess would be Challenge Cutlery Co., Baldwin, or maybe PAL.
 
No chips in either scale.  All blades open and close.  Snap on all blades.  The blades have been sharpened down but a lot of life left.  SEE PICTURES.
 
3 7/8" long when closed.
 
THIS COULD BE WORTH MUCH MORE THAN I AM ASKING DEPENDING ON THE MAKER.
