I believe this to be quite rare a 1 of it was Presented by W.BRO T.M CALVERT 1967 to the Duke of abercorn lodge no 36
It is stamped Silver 4" high x 2.5 " wide it is quite heavy I think it's more of a hanging Pendant as there's a link on it in excellent condition considering age of it
Wasn't sure how much to start the auction at
Many thanks for looking
