Unidentified silver and burl wood tray

Hello all,
First time posting, so i was only allowed to post one image .I may be able to post more on request ?. The tray has four distinct hallmarks including a right facing standing lion on a thick silver rim surrounding the wood.The silver is fastened to the burl wood (possibly birds eye maple ) with hand made screws. The bottom is lined with felt but i am not sure if this was a later addition .I would love anyones input on the marks on this tray. Thanks in advance !
