The foreign Krags are a complete unknown to me.
However, I searched sold listings on GunBroker for you.
I found three that sold in full military garb for $1,326, $905, and 935. They all had quite a few bids to get up to that point which suggests a healthy appetite for them in the market.
One wouldn't be too far off to say it's worth about a grand. Give or take based on condition.
