Silver plate bought in South Africa help with a value pls

Hi guys I bought this silver tray at an Action in South Africa , was wondering what would the value be . I believe it is very old , size is 42cm on 68cm . Any help will be highly appreciated.

The manufacturer’s mark is that of Boardman, Glossop & Co of Sheffield. It dates from late 19th or early 20th century. For value I suggest you try to find something similar in Ebay’s completed auction lists. Remember that for electroplate the plating condition is critical - any damage or wear will seriously devalue it.
