Vintage B&D corded power drill + finishing sander attachment (Upton CH49)

Vintage corded Black and Decker power drill + finishing sander attachment. It drill probably from late 1960s/1970s. Had this since new but I've lost the box, so don't have model details or specification to hand. Has been unused for a number of years. . There's evidence of its age and use - some rust marks on the chuck, and some loss of the colour finish from the casing, but it seems to work fine. Chuck diameter about 8mm. Chuck key included. There's also the Black and Decker D988 finishing sander attachment (see instructions photo). The drill is not hammer action.
