The markings on the blade are very faded, but I can see that it’s a Craftsman. It looks a lot like the 3619 at the bottom of page 29 of the 1957 Craftsman catalog:
CRAFTSMAN Back or Miter Saw. Heavy steel rib on back edge for extra strength, rigidity. Thin-gauged for cutting light stock, moldings. Fits any standard size miter box. Carefully filed sharp teeth. 11 points to inch. Pressure-welded 7-ply laminated wood handle.
9 C 3619-16×3 3/8-in. blade. Shpg. wt. 3lbs. 4oz.. $3.85
