Yes looks like a nice example of the army model C-as you can see from the pictures the quick way to tell is the stepped barrel. I have never seen one in 30-06 but the roll stamp on the ring does'nt lie when it says "U.S. 1906". It has the k98 type front sight and mauser checkering but does not have the tangent rear sight. It is possible that it was changed out after it left the factory or came from the factory that way. Hard to tell from the pics but it may be a 1 standing 2 folding rear sight. All the examples I have seen have the military type tangent sight.
