This one is 1896-1917 vintage, 1918 and later the handle changed design.  It was restored at some point in its life as there are some polishing/wire wheel marks  on top of some minor pitting on the blade and spine, and there is no dark patina on the brass bits.  Applewood handle is in great shape.  Straight spine, slightest bit of wave to the blade which you could straighten out if inclined.  Great user - sharpen it and send it!
