You have what appears to be a RC (Russian Capture) K98k, from the condition of the bluing on the receiver (red tint) and the red shellac finish on the stock.
Out of curiousity, what is the code on the top of the front ring of the rifle?
This will tell a LOT about your rifle.
Here is what mine looks like after cleaning it up.
This rifle was in the same basic condition as yours, when I took posession of it.
If you look at the forward end of the stock, where the band is, you will see where a piece of the stock had to be glued back in. The stock was 'repaired' by the Russians, apparently, and the glue disolved when I was cleaning the stock. The piece is now epoxied in place, and I don't expect it to ever come back out.

Better living through chemistry!!)
This rifle will shoot 1-1/2 to 2" groups at 100 yds with Yugo '70s surplus ammo off of a 'Bulls Bag' (IF I do my part!!!).
Cost of my byf43 K98k. . . . $219.00
