Copper box handmade - arts and crafts? Art Nouveau

This is a really lovely hand crafted box.  Judging by the material used and the design of the box I feel that it was made during the arts and crafts period.    Art nouveau?  It has Holman Bros as well as Fraser and Chalmers (S.A.) Ltd on the botom plus D.C.O.   The inside has a wooden lining. The box has a couple of dents on the lid and on the body from use and time.  I find this quite a lovely and intriguing piece.  The bun feet seem to be made from brass.  If you just love boxes as I do this is one I would recommend.   Dont hesitate to ask any questions. Please look at the pictures carefully and dont hesitate to ask any questions.
