Wood Inlaid Box

I was given this box about 25 years ago, and I believe it was bought in England around that time. It's handcrafted of wood (not sure what kind), with inlaid hearts and a bone shape in lighter wood on the top. The box measures 12 inches x 7 1/2 inches x 4 inches, is pieced with dovetail joints and has brass corners and hinges. The inside is not lined, but has wooden slots and a removeable divider lengthwise down the middle. The inside of the box top is signed by W. Howby. The inlaid key hole surround is made of either ivory or bone, and is a heart shape. However I do not have a key for it (it's unlocked.) It's a beautifully made box, and I am curious as to its history and value.
