Can you please tell me about these forks

This box of of 6 small and one large fork are believed to be very old as they came from my mother’s estate. The box is branded - Best Electro plate - Made in England.
Can anyone advise the approximate age, use of the forks and estimated value.
The mint mark is CW EP NS RD No 51170.
Thank you.
