Weatherby Olympians were built by Nikko, the same company that built the Winchester 101 and 96. The Olympian is a lightly engraved version of the Winchester 96, with much nicer wood. They seem to sell for $750 or less at most of the auction sites. I haven't used one, but they should be very reliable based on their Winchester heritage.
