Hi Farkey--You certainly did land on "the nicest 1903" you could find--they're rare enough in any condition, but almost nonexistent in the shape yours is in. Was the cleaning rod in the trap also? There's a full-stocked rifle (22" bbl) at Wm. Larkin Moore right now advertised as all original and unaltered (with the exception of a Lyman sight), in what appears to be comparable condition to yours, for 6k. That might be a bit high, but a guy could look a long, long time for a like replacement. Did you buy yours through Westley in the UK, or here in America? If you haven't already, you might try running the serial # on the Griffin and H. research page--if the gun ever passed through Abercrombie and Fitch, you can learn some interesting history about it. If you have time, could you post a close-up pic of the forend checkering? I need to have mine cleaned out (it's the later hourglass pattern like yours), and the checkerer might find a good visual helpful.
Best,
Malcolm
