Paul, I'm open to correction here, but I believe it is Japanese c.1890 ish (it could be earlier but I think around then). it has Mount Fuji on one side. The detail on the door fronts is lovely, all raised off the surface, layers of lacquer and gilding. The sides are gilded with incredibly detailed pictures. I've not managed a decent photograph of those sorry.
I believe it is impossible to renovate or repair lacquer work sadly, well certainly to the extent this piece is damaged. I think originally it was covered in some kind of chequerboard (silver? and black) all over, it would have been a fabulous piece and certainly done by a serious craftsman I think. I've attached a pic of one of the escutcheons, they are all different, some are moths, some butterflies. As it stands I don't think it has saleable value really (despite me buying (sorry, 'rescuing') it 20 years ago in the same state
). But it has beauty and a lot of my history in it, as well as it's own history, so I hang on to it as best I can.
Glad you like it.
