Sorry I am late to the party, the gentlemen here have given you accurate info and your guess of late 1957-1958 is correct.  As 3Dub mentioned, if it has the rounded forend tip as opposed to the angled tip it would be a later version.

Also, the date stamping of the barrels was discontinued in 1956, there are no dated barrels after '56.

Best Regards,

Jeff

  That old Dodge Cummins TD will undoubtedly make the round-trip to Cody for the 22nd straight year.  404K miles and still going strong!
  

I'll be bringing my 2015 diesel Ram. Perhaps yours and mine can get together and yours can share stories of the "good 'ol days" before DEF and emissions equipment!
  

... and better fuel economy!  I have a 4" straight exhaust from the Turbocharger all the way to the bitter end of the tail pipe.

Jeremy…. I haven’t found my “nice condition” sight box…. Very frustrating.  I will bring a “2 leaf” loaner for you if I can’t come up with it before I leave tomorrow… 
  

Roger that! I must've thought you didn't have one, not that you couldn't find it! Make sure to check the "sights for annoying new guys" box.

Ben-
Won't do any good to tempt me, checkbook still in rehab and recovery will be a long process. Looking forward to seeing you and any shiny bits you bring. Don't forget Jeremy's sight, we're both looking forward to shooting that carbine. The 32 fan club might just have a new member soon!

I already hounded him twice! He's still looking for me one, I hope someone pulls a rabbit out of the hat or there's just one magically there.

Bert. first of all can you attach a trailer hitch? 2nd, will it pull a trailer up the mountains? 3rd, what mileage then?  Reconsidering?
I will believe it when I see it. Don
  

Don't know, really don't now, and know idea! Final answer... Yes!  That old Dodge Cummins TD will undoubtedly make the round-trip to Cody for the 22nd straight year.  404K miles and still going strong!

Good grief.... I thought Texans were loaded!  Since it seems nobody on WACA has any green to part with, I might just have to bring S&W's to the show... sheesh. 🙂 
  

My current ride is great on gas even if it prefers 91 octane. Problem is all those windows, doors, siding, trim and new roof from that tornado blew away any fun money I may have had. Besides, herd needs a bit of thinning.

Jeff's book indicates the "everything-chrome-plated" took effect December 1957/early 1958.
Is the forward end of the stock angled up to where the stock channel meets the barrel or is the end rounded off on the top to curl back slightly toward the receiver? That round off change was made 1959 and continued until end of production (1959 for the peep-sighted version and 1963 for the open-rear sighted version).
  

I would say the tip is angled up to the barrel . . .and it is the open-rear sighted version.
Given this, I suspect I have the “Dec. 1957/early 1958” version.
Also, the receiver is slotted for scope mounting.
  

According to Jeff's great M-69 Book. The slotted receiver was first done by Winchester on this model in June 4, 1954, for the Winchester, clamp style scope rings, naturally. Many of us collectors refer to it as a, "Grooved Receiver"!

Any pictures to go along with you're descriptions?
