Pollard Glass Top Display Counter

This display counter is quite a long piece.  I’ve taken pictures of the front and back of this piece.  Inside the glass display case (of which I have replaced the top glass with a piece of glass that was less scratched) there is a label indicating that it was manufactured by Pollards and it has a number of Patent numbers indicated.  On the back of this piece, there are a number of drawers – some of which I think may be missing.  Some of the drawers are wobbly when pulling them out.  I also took a picture of one of the drawer handles – this particular handle has ‘Pollards & Co, London’ stamped into the brass.  I don’t know any history behind this piece.  I would just like to know an approximate value of this piece.
