If all parts are original, no parts updated, never arsenal overhauled, multiple thousands
Up to 1000 USD depending on how original the parts are.
It depends on the actual serial number, which is located on the receiver.
The steel part on the top of the gun where the gun can eject the bullet/reload.
That the barrel (not the gun, the BARREL) was made in June 1944. Posibbly an M1 Garand, or an 1903 Springfield?
The Garand is a highly collectible rifle. The last of the MILITARY Garands were made in the 1950s. If you have an original, military, unfired, new condition Garand (and not a rebuild) the value can only be determined by a competing buyer sale, such as an auction. Depending on which of the models of the Garand, this could be several thousand dollars. One that has been used but is in original excellent condition would be over $1000. PS- only unfired Garand I have seen is in a museum. Ft. Benning GA.
I would guess original and unfired about $900 plus or minus
Sights, barrel and bedding.
Well- there is a problem. There was no such rifle in the US military as a "tanker" Garand. There were several versions developed for testing, but there were problems and they were not put into production. There have been several companies making what they CALLED a Tanker Garand, but there is no standard design. They vary between 6 and 8 inches shorter than the original M1 Garand.
It depends on the condition of the rifle. Are all the part original? has it been refurbished?
No, just stamped on top end of the receiver. often numbers or letters on a stock denote a weapon assignment or quick inventory.
No, some did have draw lot series numbers & part numbers. The only part with a serial number is the heel of the receiver.
Roger Garand was born in 1922.
