Tom Scott Antiques has dated this piece to the 1860s.
Campaign furniture was always made to the very highest standards, but there are still stand out pieces amongst familiar styles, such as this with the additional shell and fan motif inlaid to both sides of the box and also the condition and originality of the interior, for example still retaining its original ink well with remnants of old ink!
You will then see on the underside, there are two further brass push buttons to release the top and close it up.

Super condition and has cleaned and polished up very well, although I have left the interior as found, which appeals to my own taste, but if you would prefer this to be coloured and waxed, this can be done.

Any queries or if you would like to see more, just get in touch or you are welcome to come and view / collect from me.
