OK, according to Doug Murray's book on the Savage 99, it looks as if there are two appropriate buttplates for a 1914-era rifle.
The first shows the profile of an indian chief facing left surrounded by a ring. Inside the ring at the top is Savage, at the bottom is Quality. Two "extensions" or tabs on the ring, one top, one bottom, say Trade and Mark.
The second is an oval. The indian chief is facing right and brandishing a rifle (considerably more warlike). At the top of the oval is Savage. The word quality appears at the 3 o'clock position under the indian's arm. At the bottom of the oval in the 6 o'clock position are the words Trade Mark.
According to the rather incomplete chart in Murray's book, both buttplates have been seen on rifles up through the 1920s.
