Thanks guys, not the answer I was hoping for, but a lot of good info from you. The top of the case has embossed the letters
"W A F" with a partial shipping label that says Northern Railroad. The rifle appears to be little used with bright bores and no frosting or pitting. The rifling appears to be the "semi smooth" type that Holland and Holland used.
Thanks Tim for the lead on Keith Woodvine, the serial number of 4168 would indicate a date of around 1888.
