St Peter's Hospital for Stone,Covent Garden,Silver Nurses Badge

A Silver and Enamel Nurses badge for the Urological Nursing Course at the St Peter's Hospital which was located at 27 Henrietta Street,Covent Garden,London.The hospital closed in 1992 when services moved to the Middlesex Hospital.
The badge features the crossed keys of St Peter and the motto Infirmos Curate-Heal the Sick. Unfortunately this badge has received a knock at some stage leading it to become slightly bent,as pictured.It is also missing its pin.All that being said the enamel is still intact and it is an uncommon badge.
Makers mark for WHD(W H Darby & Sons Ltd),hallmark is faint but I believe for 1965
