WWII Corsair Cockpit Interior

The reason that the Lancaster had such a long bomb bay was because one of the design specifications of the Manchester was that it must be able to carry torpedoes and as the Lancaster inherited basically the Manchester fuselage it also inherited the long bomb bay. I have never heard of a Lancaster ever actually caring torpedoes or deploying them; does any-one know if this was ever attempted from a Lanc? It must have been tried from a Manchester as this was a design spec, although it may have only been tried.
