New M1 Garand Owner Looking for Knowledge/Appraisal

Hello everyone!! Brand new Garand owner as of today; 1943 Winchester receiver/barrel with LOTS of WRA parts. Curious how much of this is actually Win other than the items marked WRA. I forgot to photo the barrel but it does have the oval WP proof. Trigger guard is also WRA. 46025 W.R.A. with white letters.
Barrel and Throat are 2+

Follow the link for the other photos I took and if I missed anything PLEASE let me know!

1943 Winchester M1 Garand WRA - Album on Imgur

Been reading, but I would really appreciate an expert read on what I own and an estimated value (so I know just HOW happy to be). Lifelong ownership dream fulfilled so I won't be upset either way.

Stock, op rod, trigger housing, rear lock bar site aren't Winchester. value 950 plus

If the barrel is correct and matches the receiver and not the 1960's Winchester replacement along with the Winchester bolt you have a nice barreled receiver . The other missing parts will cost $1200.00 or more to have a all Winchester M1 the stock will be hard to find in good condition , I saw one a year ago that sold for $750.00 that was in very good or better condition . Start looking for the missing parts to get it as close to correct as you can , nice start to having a complete Winchester .

Is this a rifle from the CMP or a private purchase?
