Unmarked 12" lambsplitter with heavy and narrow blade profile that looks a lot like the Russell pattern with boxy tip from the 20s or 30s. Just a guess.

Blade is carbon steel with a fresh convex edge with microbevel, it had been sharpened a bit poorly at the edge but not heavily and no damage or abuse, hardwood handle is nice and secure with large brass rivets. 

12" blade, just under 3" at widest point, 17.75" at widest 37.8 oz
