Hello Mike

From what I see, the rifle is serial number 201?N built in 1910. It appears that it was originally produced as a 4* pattern, then converted to a 3* pattern before making its way into the U.S. There is a letter stamped in front of the letter "N" just to the right of the serial number, can you tell what the first letter is? It doesn't show up in the pics.

There appears to be a unit marking, or part of a unit marking shown in the pics that I cannot decipher.

That's about all I can come up with.
