Earthenwares, Second Pre-Fix Letter
About 1920 a second letter, K L or M was added to the Queen's Ware pre-fix numbers in order to show whether the painting was:
K Underglaze
L Under and Onglaze
M Onglaze
Earthenwares, Third Pre-Fix Letter
A third letter H was added to those patterns that were free-hand-painted.
Bone China Second Pre-Fix Letter
Except for one colour prints, practically all bone china patterns are onglaze so that no distinguishing marks are necessary. However, if the pattern was free-hand painted the letter H was added to the first pre-fix letter and for 'Decal' coloured prints the letter D.
