Mayer China Date Codes

Date coding is simple for Mayer China: usually a 3-digit code, first number represents the year quarter and the last two numbers represent the year. Early Mayer does not appear to have a date code (pre-1950s) so back stamps should be used to date china. It is unclear as to when they stopped using this coding system so we just continued it until 1999 to finish off the table though they may have stopped using it in the late 1980s/early 1990s.
