THIS IS AN OLD CASE XX!  Right from an estate sale. 
 
CASE XX double blade.  I believe it was made between 1965 to 1969 but may be earlier.  Larger pocket knife also at 3 1/4" long when closed>
 
Condition:  Both blades open as they should.  The smaller blade has snap but the larger doesnt.  No wobble.  The front handle has no cracks or chips but the back handle as seen in a few pictures.  The knife is missing one pin.  SEE PICTURES.
