Hi Wilbur, it signifies a chassis that was originally built for export. Obviously it was built for sale in a country which was on the 110-120 volt AC standard, which would leave out many parts of the world which used a 220 volt AC line voltage. It may have originally been sold in Mexico; I know of a 16B that came from Mexico with a metal tag like that.
