Puckerings has dated this piece to the 1850s.
The wood is trimmed with polished brass with a clasp keeping the book closed, another bonus for this example is it still retaining it's original leather covered storage box which has clearly done a great job protecting the book.

Once the interior is inspected, it is lovely and clean. Excellent condition measuring 5" x 3 1/4" x 1 1/2"; the case measuring 5 1/2" x 3 3/4" x 1 7/8".
