Riverrat,
That's pretty cool, your rifle was made under 6,000 apart from mine, and I just got mine last week. I guess yours is probably more orignial than mine, since it would seem mine has been re-parkerized at some point. It is interesting to compare the parts drawing numbers to see how yours and mine differ since they were made the same month. You can see pictures of mine in the post "I think I found a winner" on here. I upload my pictures directly to milsurps, as described in the sticky thread located a few lines above your post titled something along the lines of "how do I upload pictures to my post for storage on the milsurps.com server". I would be interested in seeing a picture of the chamber mouth of your rifle, as I'm still trying to figure out some questions I have about my own. Anyways, I think it's pretty neat that you and I acquired rifles so close togetther in production date just a week apart.

This is an interesting spreadsheet that tracks the part drawing numbers on your parts and compares them to your serial number to determine liklihood of origninality. Of note, I've found some things in the spreadsheet that popped up as questionable, but upon cross-reference with Poyer's book turned out to be quite standard.

The GAW and NFR stock cartouches seemed to have a period of overlap in October/November of 1944. Examples would seem to indicate that your GAW stock, if anything, is more likely to be original than my NFR stock, but I'm no expert, I've just been reading my butt off the last couple of weeks. My bolt has some black parkerized parts (extractor, for instance) with the bolt body parked in gray. Does yours exhibit this? Also interesting is that both our barrels are 10-44 dated, but mine has an extra dash compared to yours. Mine is marked 1-S-A-10-44.
