Model of 1917 by Winchester - sling swivel markings

Hello,
I understand from the following website - U.S. Rifle M1917 Markings
that the BUTT swivel is the only swivel winchester marked along with the BUTT swivel bracket which is also marked "W" -the stacking & middle swivels are not marked but the front & middle bands are. I have all those pieces.
Anyway I'm trying to find/buy 1 "W" marked sling swivel to go alone with the butt swivel bracket I have. It does not have to be perfect 100% blued. It's going on a "USED" rifle so it can show honest finish wear but no rust or pitting. Now I'm getting picky -huh?
Please if you have or know where I can get one please drop me a line.:surrender:
Thanks for the time

an unmarked swivel would be correct for a Winchester. some were marked W some were not.
its tough to spot the W in some parts, N.S. would also be a Winchester mark as well,
VP in a circle is also a Winchester only marking..as is MVS

Hey Chuckindenver,
Thanks for the reply
Not at 8000ft anymore - over the hills in Delta Co. now.
