In February 2015, a1903A3 National Ordinance Military rifle in good condition (matching numbers, shootable) is worth approximately $ 900 - 1,300 depending on the rifle's actual condition.
The Model 1903A3 rifle is base upon the Mauser 98 action but they are not exactly the same.
With the serial number that you have supplied,your Smith-corona model 1903A3 was made in the year 1943.these rifles were only made in the years 1943-1944.If your rifle has a letter C prefix to the serial number,then this indicates that remington also made a model 1903A3 with the same serial number. These were the only 2 manufactures of the 1903A3 rifles.
For which nation? There were different countries with different rifles. US- 1903 or 1903A3 rifle, and the 1917 rifle Britain- SMLE Germany- 8mm Mauser 98 Russia- 91/30 Mosin-Nagant
With the serial number that you have provided,your Remington model 1903A3 was made in the year 1942.The first serial number assigned to this rifle was serial number 3,348,086,So as you can see yours was made early on in World War II.
Well, we CAN tell you that it is Italian, and lkely a military rifle- since Terni was the national Armory for Italy. Beyond that, we need some description.
The Garand rifle is a semiauto, not a bolt action. Do you have a Model 1903A3 bolt action? A Model 1917 bolt action?
The fireball that you mention is actually a bursting bomb.This was a mark from the ordinance dept.of the U.S. goverment that was imprinted on most U.S. military weapons.
Typically, yes, it does. While M-1 carbines were made after WWII by NON-military suppliers, those made for the US Military are typically marked with the "Burning Bomb" stamp.
Terni was the national armory of Italy- you likely have an Italian Carcano military rifle- but we can't tell you more without more information. Sorry-
