My guess is; Since Savage didn't put caliber markings in front of the receiver,and since it had to have the only barrel address (.303) available at that time to be a legitimate Savage , and since anyone would soon find out and wonder why a .303 Savage would not chamber in a .303 marked gun and would soon say - it must be - - let's try a 30-30, (the only other popular modern cartridge of the day). They either made one up in secret, not telling the boss, who was only interested in the barrel address anyway, and never checked the chamber; Or it was made up as a test rifle , to see how it would handle the 30-30 in case they decided to make a new 1895 in that caliber. Called an 189_.
