I have the same rifle so my oldest is also from 1884. (wish I also had a 1873 lol)Model 1884 Springfield Trapdoor.
I have a Savage Model 3A, it was my grandfathers, made in 1933.Savage Model 3 - 80 yrs. old.
It is. The receiver is in the bottom 1/8 of the picture. The Russians/Soviets stamped the date/mfg/serial on the barrel.I thought a 1929 would be a hex receiver.
