I see that your rifle has some special order features ..... half octagon barrel and button mag. That tends to raise the value several hundred dollars. It is hard, however, to get an accurate feel from the photos as to how much wear it has, and whether there has been any re-blueing of the receiver (if it is original, you should be able to see striations along the sides of the receiver from the original forging) or sanding and refinishing of the stock (would should be proud or at least flush with the metal). I don't think the barrel has been re-blued. Another factor is the condition of the bore. Does it have strong sharp rifling with no pitting, or a wee bit of very light pitting here and there, or is the pitting quite noticeable and the rifling about half worn down?
I'm going to give a tentative estimate as to the value of this rifle, but given the steady exodus of old Winchesters to the USA over the past 6 months, I might be on the low side, but here goes .....
If the rifle is unmessed with (no re-blueing, no sanding of the wood, no chopping off a bit of the muzzle, or reducing the length of the mag tube) and it still has roughly 60% of the blue on the barrel, turning more of a plum patina, and if the bore is good with strong sharp rifling and only a tiny bit of pitting here and there, then given that it is a half octagon with a button mag and assuming that it will letter that way, then 12 months ago, I might have said around $1,200 to $1,500. However, with the steady drain of desirable Winchester to the USA, that might be a bit on the low side now.
When you put it up for sale, you really do need to take more photos so prospective buyers can decide its condition. One of the right side of the buttstock, one of the right side of the reciever, one of the right side of the forearm, and one of the right side of the barrel, then the same for the other side. Then one from the top showing the rear sight and the front of the receiver, then one of the printing on the barrel. Photos should not be dark or blurry.
