In A Nutshell Antiques and Interiors has dated this piece to the Victorian era.

The retailer's name "Finnigan's, Manchester" is embellished in gilt writing on the inner edge, a renowned retailer of luxury goods. The lock is stamped "T.Turner & Co, London".
The box comes with a working key and it has an unusual locking mechanism where the brass escutcheon is pushed up and right to release and lock the catch.

The box is in very condition for its age and has a beautiful rich patina. The outer has some small age related knocks and scuffs and there are some small losses to the underside. The interior is generally clean and tidy and it is certainly a usable item.
The best description comes from the photos so please look at them all carefully and if you have any questions just ask.
