Sinclair Cambridge type 3 calculator from 1975

Box is tatty with flap loose but does still have the insert sleeve

Hard case snaps closed

Calculator itself suffers from the usual dodgy power switch. So you get random displays and responses to buttons being pressed

However the LED does light up nice and bright

Battery cover no longer clicks but has not been selotaped as you normally find

Interestingly the battery cover already to be from a type 1
