Hard to find!  Good chance for a collector.
 
"JOHN PRIMBLE BELKNAP HDW INC".  Model 5390 as marked.  Marked with the Star also.  This company made knives from 1940 up until 1968.
 
Beautiful brown 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 handle looks fantastic.  Polish or keep the patina.  All blades still have snap.  SEE PICTURES.
 
2 3/4" when closed.
