it's hard to say what it's worth because sometimes one little stamp or feature is more or less desirable to a collector. if you pull the bolt and then look at the bolt face, does it have a flat bottom as you have it right side up and looking at the bolt face?
the small rings were made before metallurgy and gun design were at their peak and so are not as safe as later models like the 98. nothing wrong with your rifle though. i'd have a gunsmith look it over and make sure it's safe and then enjoy using it.
