Bad news. I brought the rifle to my smith and he informed me that since it has a serial number under 800,000 it would be dangerous to shoot. 326001. Real bummer. Easy come easy go I guess :-(
A "low number" Spingfield is indeed one below 800,000 (for Springfiled Armory -- "low number" Rock Islands are below around 250,000.)
However there are
no "low number" M1903A3s. The "low numbers" were made prior to WWI. M1903A3s were made during WWII, about 20 years later.
Take a look at your rifle. If the rear sight is mounted on the barrel, ahead of the receiver, it is an M1903, and if that serial number is right, it is indeed a "low number."
If the rear sight is a peep sight mounted on the receiver bridge, just in front of the bolt handle, it is an M1903A3 and cannot possibly be a "low number" Springfield. Also check the maker -- that's marked on the receiver ring (where the barrel screws in.) "Low number" Springfield were made
only by Springfield and Rock Island. M1903A3s were made by Remington and Smith-Corona.
If it is truly a "low number" Springfield, do not dispair. The Army thoroughly analyzed the problem and did
not withdraw "low number" rifles from service. They were left in service until they wore out and were turned in for repair. Once repaired, "high number" rifles were returned to the unit, "low number" rifles were placed in war time storage and a new rifle was issued to the unit.
The Marines
never turned their "low numbers" in. When a USMC "low number" came back to the arsenal for repair, it was repaired and returned to the Marines. Many a Marine who landed on Guadalcanal carried a "low number" Springfield.
A recent analysis shows the danger in firing a "low number" Springfield is lower than the danger in smoking a couple of cigarettes.
