I think this company, "Shanghai Xin Min Commercial Co., LTD." is the maker of many, perhaps most or all, of the Chinese resonator guitars. There are a boatload of links to this company around the Web. Their claim that their luthiers has (sic) 8 years of experience manufacturing these points to 2001, when the Johnson (U.S. brand of Music Link, Inc.) resos switched from being made by Amistar in the Czech Republic to being made in China under the AXL name.
