Any idea what it is worth?

Barrel is dark, wood is good, metal has some freckling, I wouldn't be surprised to find some fine pitting if I had a chance to look it over further. But the Elmer Keith history is kinda neat to say the least!

I saw one with a Keith cartouche amongst the American Legion trade-in rifles at CMP last summer. It had a South Dakota American Legion decal on the stock, (Post #7?). On the outside it was in fair+ condition. The bore was rough from shooting ceremonial blanks. I believe they were selling them for ~$375.
