This is an old one worth restoring.  New York Knife Co. with bone handles.  Also marked Hammer Brand.  I would estimate this to be from 1878-1920.
 
Selling as a parts knife or knife for restoration.  Epoxy may need removed from one handle and bolster.  The smaller blade is broke.  The main blade has great snap left.  The rear handle is in great shape.  The knife still has both bolsters and its badge.  SEE PICTURES.
 
2 7/8" when closed.  Double blade.
