No idea on the Belgian model but a Russianicon Nagant revolver that has not been refurbished and is not import marked is in the neighborhood of $300. A leather holster is about $60.

The $100 Nagant revolvers are all Soviet years, been refurbished, are import marked and may have re-stamped serialed parts. They are not necessarily collectible but they are a blast to shoot. They also come with the imitation leather holster.
