I guess I have been out of the loop too long. i didn't even know Japan manufactured some of the weatherbys.
Found this on the weatherby site:
You can learn the history and lineage of your Weatherby firearm, researched and authenticated through the Weatherby company records. You’ll receive an embossed letter of authenticity which verifies the country of origin, the date your firearm was shipped, where the firearm was originally delivered and a list of features, including any custom embellishments. Each certificate is personally signed by Roy E. Weatherby, Jr., President, and Dean Rumbaugh, Company Historian. Cost for each serial number search is $50 ($75 for Custom rifles, $100 for Special Edition or Commemorative rifles). You may print and mail the Authenticity Order Form or for information, write Company Historian, 1605 Commerce Way, Paso Robles, CA 93446.
