Does anyone know what the number on the bottom of these table stand for? I have 2 blonde ones with beige metal legs and a brown one with black legs (T341374). The other 2 are in a packed closet, so I don't have the # on them. All have T and 6 numbers. One is missing the basket, but all are in excellent shape. Does anyone know where to find a basket as soon as I figure out what machine goes into it.
