w t crown and deer

Hi,

I have just aquired a brooch depicting a stag hunting scene.
It has been made from the top of a box ( hinge still attached ).
The mark on the back appears to be W T( each letter in a separate square box) followed by a crown followed by a deer lying down(again in a square box)
The hunting scene appears to be cast, the hallmark?appears to be on a lining to the lid to which the pin is attached.
Sorry no photo at this stage, yet to work it out!
Any ideas on the mark, it’s definitely a deer rather than any sort of lion.
