This is a brand new metal 1250 scale model of HMS Endurance, a Royal Navy ice patrol vessel from 1967 to 1991.   She had a bright red hull, as is common for polar vessels to aid visibility but otherwise uncommon for the Royal Navy, so her crew nicknamed her The Red Plum. Endurance was equipped with a signals listening suite on top of the hangar.  This is the peacetime version with A171 on her hull..  Cat ref N71x   Length of the model is 75mms or about 3 inches.
