That's what we thought too, from looking at '94 Winchesters, rifles and carbines from early 1900s.

739xxx would have had its serial number applied in October 1920.

Thanks, Tom. Can you provide your source as that is different then what I found, linked above?

Winchester Polishing Room Serialization Records. They show when the serial number was applied to the receiver. They are the most accurate way to date a Winchester. Most all of the other serialization tables are incorrect or have some errors in them.

long overdue. got busy.
So the topic I promised was rust bluing with these "flaws" in the metal that was producing the striations which wear faster than the surrounding metal, and then look like long deep scratches after 100yrs. After lots of trial and error with the last 97, this one went along pretty uneventful.
as soon as you degrease, these lines flash rust, deep and fast. Don't worry. just don't let it sit - go ahead and wipe on your first iteration.
I'm using mark lee's express blue no. 1. you can see the striations aren't playing nice. Just ignore them and keep going
it gets worse in the boil. now, when it comes out and after carding, grab a square of clean paper, and lightly go over the area until the lines disappear. In my initial prep, I usually finish with a piece of worn paper, so I go one step of finer grit this time so there is nothing that stands out. The etching of the rust process will make any variation irrelevant and unnoticeable in the end, so long as you finished at ~320grit or beyond (depending on manufacturer of the paper. no benefit to going finer than needed. 400 seems to be a good number that works across many brands, even the cheap stuff.) You can't see it, but there is just barely enough magnatite over the striated spot to keep it from flash rusting again, so at the next application the striations catch up.
here we are after the second application, just before boiling.
now where did I save the final pics, with the bolt and everything? ugh.
