We are not sure of the maker.  No tang stamp.  There is a mark on the blade as seen in pictures...Im not sure if it is a makers mark. I am guessing this was made in the 1950's.  Double blade.
 
BEAUTIFUL AND COLLECTIBLE HANDLES DESIGN!
 
Light signs of age as seen in pictures.  Both blades fold out as they should.   Great snap left on both.  One blade has a chip.  Bolsters and shield have some signs of age.   SEE PICTURES.
