BEAUTIFULLY AGED...1920-1940...pre-war.  THIS IS AN OLD CASE XX!  Right from an estate sale. 
 
CASE tested XX.  DOUBLE BOLSTER AND DOUBLE BLADE.  3 5/8" long when closed.
 
The tang stamp is hard to see but it has the circle C Case text which is underlined.  It states Tested XX under.
 
REAL JIGGED BONE HANDLES.  The front handle is a dark brown.  The rear handle is a tiny bit lighter in color.
 
Condition:  All original.  Still has its badge.  Both blades open as they should.  The smaller has absolutely no wobble.  The larger has very small amount of play side to side barely worth mentioning.  The bolsters have some surface wear.  The smaller blade has snap left and the larger doesnt.   The rear handle has a hard to see hairline crack that isnt open and doesnt affect its stregth, etc.  SEE PICTURES.
 
GOOD CHANCE FOR A COLLECTOR!  One of these recently sold at auction for $437.15
