Help with maker I.D. and age- Match Case

I obtained the item here recently and know little about it. I believe it is a Sterling Match Case. Can someone assist with explanation of the marks by the maker and estimating the age. Thank you.

 

Birmingham 1894, maker probably Minshull & Latimer.

The M&L is the sponsors mark, the lion signifies Sterling silver, the anchor is for the Birmingham assay office (UK) and the 'u' is the date letter.

Edit: Just to add we call these a Vesta Case in the trade
