Here are some notes to help date any piece that bears an English registry mark.A diamond-shaped registry mark was used between 18.The number listed for each year in the table is the first number issued that year. If your number is higher, but less than the number for the next year, then your item had it's design registered during that year.The Public Record office and the British Government tend to enforce these marks and registration numbers.From the other numbers and letters we can work out the date of the registration.The diamond-shaped English Registry mark, was used by the English patent office since 1842 to identify pieces of English pottery, porcelain, and other products. The mark has the Roman numerals "IV" at the top of the mark if it is for a ceramic. Marks registered from 1842 to 1867 have a letter at the top of the diamond.Between the initial filing or application and the final granting of the patent the filing number may be used to identify the patent.So a number lower than 100,000 may be a patent issued before 1916 or a filing number issued from 1916.

An item with a registry mark or number could have been produced before (less likely as the design would not be protected), or after the date of the registry mark.

As well as showing that the design had been registered, diamond mark offered the buyer the reassurance of knowing an item was of British design.

It also assured the person registering the design a degree of protection from copying.

Companies located outside the UK who have reproduced items, and tried to use a facsimile of the marks or numbering system have been sued, and have had sanctions imposed against them.

This tends to protect the use of these marks, and in general restricts them to use on pieces made in the UK.
