Poor to fair. Slight foxing and browning in books. Sun fading of spines. Bumped and scuffed covers and corners. The 1942 slide rule has ink annotations, and the other two slide rules have scuffs commensurate with age. SLides are scuffed, repaired and taped. Mechanical slide rotates with ease, with slight corrosion to fasteners. 7 slides lack wooden frames.
