Your rifle's receiver appears to be polished and blued.See below and refer to old advertisements for deluxe vs standard grade rifles.
Repost from the Late and well liked Brian Alpert:
In my 25+ years in dealing with JSARS, I have come to a number of conclusions regarding value/price realized on sale. In my opinion, the hierarchy of value is as follows:
1. JSARs with documented US provenance and those with individual combatant provenance. Realize that only around 800 JSARs were in US service.....Marines, 1st Special Service Force, OSS, etc
2. Original mint condition JSARs with or without correct, as issued numbers
3. Originals in lesser condition
4. JSARs restored to original configuration with replacement stocks, bbl, rear sights, etc. The more replacement parts, the less it is worth.
5. Previously polished and blued JSARs restored to original with replacement parts
6. Restored JSARs with receivers drilled and tapped for scope mounts
7. Winfield Standard Sporters. These are easier to restore than Deluxe as the receivers have not been polished and blued
8. Winfield Deluxe Sporters
9. Sporters which have been drilled and tapped
Chilean 7mm JSARs (imported by Navy Arms in late 70's), even with correct #s bring less than 30/06 rifles in comparable condition. Miltech restorations are at the high end of restored rifles.
The majority of JSARs in the US came from Winfield Arms. Cecil Jackson bought the entire Dutch inventory in the late 40's as well as most of the parts inventory from Numrich and these emerged as Winfield in Los Angeles
Auctions and online auction sites are sometimes a "crap shoot" I have seen Sporters go for $5000 and nice originals go for under $4000. Occasionally, one, even without provenance will reach "telephone numbers". I believe the record is around $12000 but realistically, choice originals may reach $7500. Decent restorations $4500, lesser on down.
