I’m not into these but methinks it’s an FN made Lithuanian Model 24. I think they are hard to come by as well.
All thanks! The Belgian model of the Mauser 98. What factory in Belgium produced them and how many has been let out pieces - who knows?
Has found such brands
Very good, and very early!
Have you more images of other markings? I will contact John Wall and see if he can comment on this rifle. He would know better than I what this is exactly.
