Vintage Texas Instruments TI-1400 Battery Operated Calculator w Case *for parts*

Vintage Texas Instruments TI-1400 Battery Operated Calculator w Case This is being sold for parts. I do not know if it works. There is a battery is stuck (maybe corrosion?) It will come with the calculator as I did not want to force it apart. Stored in smoke free, climate controlled environment. Comes with case. Also, the face of the calculator comes off and would need to be reglued.
