Dating tips for English Pottery & Porcelain II

diamondmark2This is the second of three Design Registry Markings . Deciphering  the 1867-83 mark is similar to the  1842-67 example that preceded it with some changes. The Roman numeral in the circle on top of the kite/diamond still represents the type of material the item is made from. EG. , it was used for metal, II for wood, III for glass and IV for ceramics. Note, though, that the four corners of this newer marking the codes have been rearranged. In this case  the number “9” in the top position below the material mark IV now indicates the day the registration was made. The number “9” on the left corner is the “Bundle number,” the letter “c” on the right side is now the date  letter for the year (see chart below). The bottom letter “R” is now the month code.
Using the chart below, it indicates that mark  above left is a registry date of August 9th, 1870. As with the original 1842-67 Kite/Diamond marking, this 1868-83 version is also used on metal and glassware items.

The date coding is pretty straight forward for both markings, with a few exceptions. For the first mark—used from 1841-1867—the letter “R” was used during the year 1857 between 1st and 19th of September. For the year 1860, the letter “K” was used between 3rd and 31st of December. For this second mark used 1868-1883, between 1st and 7th of March for the year 1876, the letter “W” was used for the year instead of the correct letter “D,” and the letter “G” was used instead of the correct letter “W” for the month.
