Bailey-Walker China Date Codes

Pieces are date coded by mark and by code. Though some of the earlier pieces may be marked with an easy date code of a 4 digit code which represents the full year. Some of the other earlier pieces and later pieces are marked with either a single or double digit number (dash) double digit number or a letter (dash) double digit number code. Knowing that Bailey-Walker marks are pre 1942 and Walker marks are post 1942 will help identify which code to use.

1923 to 1942:
Bailey-Walker mark - Four digit number codes might represent the year produced.
