Rob, The photo is of the Kit Carson Hawken. The Davis lock I use is close to the Hawken lock, but it is different, and that is what you see. The triggers are different, too, there is no exact match. This stock is a Pecatonica. I had them inlet it for the barrel only and drill a 7/16" rod hole, and leave the breech end of the barrel inlet cut 1/2 short to have wood up against the tang. Also, I needed 3/4" more wood on the toe line to get the correct drop at heel. I had two or maybe three cut this way. I have since built two more from a blank and that way I can very closely match the Carson stock. The LAST Bridger I built was from a shaped Knob Mountain stock, I had to cut a lot of wood away to get the Bridger shape.
My LAST Bridger (way too heavy), the Pecatonica stock, and a 15/16" .54 H&H barreled Carson Hawken made with a Pecatonica stock. Note he add-on line that runs to the front of the eraser.
