The stock looks to be "refinished", which devalues the rifle somewhat. It would be worth seeing how many SA (Springfield Armory) prefixes are on the parts. If they all are, you have one of the more valuable ones.
Probably $800-$1000 depending on if it's a mixture of parts or not.
They are real quite a rifle. I just love the trigger on them.
To determine exact value, you would need to disassemble and catalog every single part. Sometimes single parts are worth a lot of money. I sold several winchester safety's for $75 each. Your barrel would have to be gauged at the muzzle and chamber, and your muzzle looks pretty worn from the pic. Any winchester part is worth more than most other parts, but there are guys looking to put mixmaster rifles like yours back to all original parts. The pay extra for H&R and IH parts too. A stock with cartouche can be worth more than the rifle. Check out Culver's website. I think someone there may have a download of a form to log your parts, but you may need help to identify them as to which year each part came from. http://www.jouster.com/forums/index.php
Here's a website where you can still buy depot storage garands. http://odcmp.com/
The prices there are about what you should expect for your garand, unless you have some collectable parts on it, and it being an early serial number in itself may be collectable.
Magnumshot has it exactly. One thing I saw was what appears to be "NM" on the op rod. If that is so, will change value for certain. For a pre-war receiver, $750 might be a little on the light side. Check out CMP and also Garand Collectors. That will get you started down the right path.
Magnumshot, you got any WRA parts? Trying to re-set my rack grade back to factory.

flabigpapa. I am not an expert but I have all of Scott Duff's books. Aug 1940 is the correct date for the receiver. I am looking at the data sheet for a
SA 56745 rifle
date manufactured August 1940
barrel side marking: S-A 8-40 [upside down]
The barrel dates closely followed the receiver dates during that period. Your barrel date does not match the receiver so not likely original. I can see from your photos that the rifle is arsenal rebuilt. The rear handguard clip is wrong, it is sheet metal, should be milled with a groove down the middle. The stock ferrule should also be milled, yours is sheet metal. The stamping on the end of the buttstock is certainly not SA, probably a local arsenal stamp.
The rear sight knobs are not original. A NM operating rod is really not unusual, won't add to the value. Looks like you have a typical arsenal rebuilt rifle, maybe rebuilt a number of times. Seems odd that it has the 10-41 barrel as the ammo was corrosive during WW2. When those rifles were rebuilt, they were disassembled and all the parts were gauged and put in bins. Then on the other end of the plant they were reassembled with the parts taken from those bins at random. So the parts were all mixed up. They paid no attention to manufacturer stamps.
The receiver looks in nice shape. The lower the serial number the more desirable to some. Don't know about value.
