Having a trawl through old TDC documents, which is a pastime of us bloggers . I came across a paragraph I found of some interest. It appears TDC are the owners on our behalf of 17,000 sea shells from areas around the world. This collection was once in display in the old Margate Library in Victoria Road and belonged to the Borough of Margate Town Council. This came about when the Library and Museums collection was divided up between TDC and KCC during the 1974 local government reorganisation and TDC inherited the shells.
According to this document the shell collection is known as the "Cobb Shell Collection" and is on loan to the Powell-Cotton Museum. I have only ever seen a few decorated shells in the Margate Museum so I assume the shells are still at the Powell -Cotton museum.
TDC has no Councillors on the Quex Trust at the moment and because I have been refused a list of the Margate collection under the Freedom of Information Act by TDC it will mean further research. Unless there is someone in blog space who can throw light on the subject.
