The Second Doctor's slim penlight prop from The War Games has been identified as a EverReady model no. 1980 (1968-70 version).

Shape of the cover ring In " Hell Bent", the TARDIS gives the Doctor a brand new sonic screwdriver. The new screwdriver has a TARDIS-blue shaft with gold and silver highlights. The upper half is a rectangular light grid that, when switched on, has four different functions: green light with low-pitched sound, blue light with high-pitched sound, green lights that pulse with a pulsing sound, and a blue light chasing pattern with a pulsing sound.
