Steven,
You didn't even mention if its a 300 or a 250???? Also, will you PM me with the details:serial, barrel length, "LBC" or whatever is stamped there, whatever is stamped on the front of the receiver, and the barrel address style number.
the only non factory thing that I see is the washers under the swivels... wonder what that was all about... and the lightly refinished wood.
A rare gem for sure and one you should be quite proud to own.
