My great great grandfather, James Cross, was Second Coxswain on the Clacton Lifeboat. In 1881 they rescued a French ship called the "Madeline" and he was given this tankard in commemoration. The inscription says:
By The Subscribers
To The Fund
Raised In Recognition Of
Brave Services Rendered In The
Clacton On Sea
James remained Second Coxswain of the lifeboat until he drowned whilst on a rescue on 23rd January 1884.
