Very Rare WW1 English Silver Military Cap Locket Pendant Reg. 642217 British

Absolutely delightful pendant in the for of a officer cap. It's British hallmarked registration number 642217. The date letter is rubbed but it's from around 1914-15,it's Birmingham and the maker as much as I see WV or WW. Such a sweet pendant locket. Weights 2.8g. The condition is as expected. Thanks for looking:-)
