I just bought an E.T. cart that had the end label stamp "462 D". I have heard that the digits are the week and year of production but what is the "D"? I have a ton of "R" stamped end labels and some with no letters at all. So my question is does anyone know what these letters mean? I did a search of the forum but it didn't turn anything up so sorry if this is somewhere else. If needed I can send a pic.
Thanks,
Jason
