Anyone know if its 1.2V or 2.4V nicad. Easy enough getting inside, battery looks like single cell as metal cladding continuous through the middle area but could it contain 2 cells , one of which is shorted. Sluggish motor

Looks 1.2V , ps 2.4V and motor runs far too fast. looks as though it was a switch problem. Running 2 to 3 amps and start 3 to 5 amps. Switch is paired up , to take current, pair of 1mm wide prism point contacts, one being dirty. For same reason that powering the motor from 1.2V via a pair of croc-ended leads drops far too much power.
It is surprisingly easy to remove the base "plug" 1/8 turn to get inside these and no wires to break so worth a bit of time to repair. Interesting , for those with mechanical bents, double crank and rubber mechanism creates the motion
