In 1938 the UK set up the Inter Service Training and Development Centre (ISTDC) to develop the techniques for specialist amphibious equipment and techniques.

It had worked out a number of procedures and proposals by the time it was disbanded in September 1939.

A revised ISTDC was formed in January 1940 which carried on from where the original ISTDC left off, proposing amongst other things the conversion of train ferries into Landing Ship, Stern Chute (LSS) and oilers in Landing Ship Gantry (LSG) for carrying LCM's.

Does anyone know of any documents on the ISTDC?
