I think he's talking about the 2 Japanese manufacturers "TOP" and "Asahi"....but I don't think Asahi EVER made metal FAMAS bodies.
He's right, though.....if you're looking for something old and rare, contact Darryl Zero on
www.classicairsoft.net forums, then find a Canadian retailer to bring it into the country if DZ finds what you're looking for in Japan. DZ also lists stuff on Ebay under the username "raresoft".
