age of this silverplate

I was wondering if I could get the age of these knives please? pic attached.

Stamp reads
James Deakin & Sons, and then an old lamp symbol, to the right of the words.


The simple answer is no, it is impossible, with very few exceptions, to date silverplate accurately. Deakins were in business from the 19th century through until 1939. From the script form of the mark it seems most likely to me that you knives date from the latter part of the company’s history.
