What an outstanding rifle. Yes, it is built on one of the Oberndorf Commercial M98 Mauser intermediate length actions with the small ring (1.300" diameter vs. the 1.410" large ring). So at first glance it resembles an M94 or M95 Mauser.

Bracebeemer: Can we by chance see a close up of the retailer's label that appears on the inner lid of the case ? Was your friend able to provide any provenance or past history on the gun since Mr. JJ Harrison bought it more than 120 years ago ?
