I have a bolt, straight handle, milled extractor, small gas hole, with D4 on the underside of the safety lug.
Also, there may be a mark on the bottom of the bolt root but it's only a partial mark as best I can tell.
For what year(s) M1903 would this bolt be appropriate?
Thanks for any help.
If pictures are necessary I can post them later.
