Weatherby Mark V
The German manufacture scopes were labeled as Imperial and had the adjustment & focus turrets located on the top of the scope. The Japanese scopes labeled as Weatherby had turrets on top for elevation and on the right side for windage. These were early version Nikon optics. If you're sure the rifle is a Mark V & definitely not a Vanguard I'd purchase it in a flash with the condition you describe. Look over on GunBroker and you can see $800.00 is a great price for the rifle alone.
