Hard to find!  Good chance for a collector.
 
"JOHN PRIMBLE BELKNAP HDW & MFG CO."  Model "4927".  This company made knives from 1940 up until 1968.
 
Beautiful jigged bone handle and the knife has the perfect amount of patina.
 
THE PERFECT AMOUNT OF AGED PATINA.  Normal signs of age for a knife this age.   The bone handle looks fantastic.  Polish or keep the patina.  Two blade still have snap left.    SEE PICTURES.
 
2 3/4" when closed.
