Folks, this topic has been an interesting read. I don’t get overly excited by it but I do wish to contribute so someone other than me can maybe make up a matrix and figure when the factory went to applying the alignment marks. Accordingly I looked at my models 1886 and 1894 to see about the marks.
MODELS 1886: sn 91108, no marks. in warehouse 9/22/94
sn 139253, alignment marks. in warehouse 3/11/1907
sn 146086, alignment marks. 1908
sn 157730, alignment marks. 1920
MODELS 1894: sn 85993, no marks. in warehouse 5/25/1900 Note: Two R and R’s and at least last was for refinish.
sn 90296, no marks. in warehouse 8/22/1900. Excellent original condition.
Hope this helps narrow in more.

Just my thoughts, the barrel is inserted into the receiver after threading, and marked for the next operation. Now it is located in the next machining operation relative to the mark on the machine. This assures the dovetails are cut exactly on the top and bottom and not tipped. Mark Douglas may have thoughts on this.

Knowing the sequence of the machine operations would certainly be helpful. I don’t. Most times it takes me a couple of tries to set up my drill press. You have a good point, it may have been for internal use but I like the theories about a wear indicator.

Good point. The whole idea of Winchester’s spirit level sight was to position the dove tails straight up when shooting long range. If every time you installed the barrel the sight dove tails were less than square with the world accuracy would suffer.
The alignment marks are very fine, perhaps to make them more accurate. Winchester on a lot of it’s early guns used alignment marks ahead of the front and rear sights on the barrel. I assume this was done if they sighted in a gun. Winchester prided themself in selling a quality product, this was perhaps the reason for the marks.
If the barrel takedown is worn and the barrel can move when firing, the barrel might be pointed off target before the bullet leaves the barrel. Maybe more than one reason for the marks. T/R
