TJR Trading has dated this piece to the 1900s.
It has a hallmarked sterling silver front cover decorated with Joshua Reynold's angels. It was assayed in Birmingham in 1903/4 and made by Charles Penny Brown.

It is 6 by 4cm and weighs 28g.
It is not in very good codition. The front cover is totally detatched and the back cover is nearly as bad. There is writing in pen on the first page, and the silver is quite worn.
