This is an old one!  Made between 1920-1940.  It has the older Case Tested XX tang stamp.
 
Single blade barlow type with only one end having bolsters.
 
THIS MAY BE A RARE ONE AS I CANT FIND ANY PICTURES OF THIS MODEL ANYWHERE.
 
In need of refurbish.  Bolsters are in good shape with no dings or dents.  Blade opens as it should.  No snap.  Some surface rust on blade.  The scales have some small cracks.  PLEASE BE SURE TO SEE PICTURES.
 
3" long when closed.
 
THIS WOULD MAKE A PERFECT REFURBISH PROJECT TO ADD TO YOUR COLLECTION.
