vintage modern toys tin battery powered twin Beechcraft non working airplane

This is a rare battery powered Modern Toys twin Beechcraft Bonanza. It is metal fuselage and wing tops with plastic wing bottom. Has couple cracks in plastic as seen in pictures on bottom leading edge of wing and a repair on back behind wheel cover. Propellers wobble a bit in engine cowlings. Graphics in great shape as is cockpit interior. battery compartment is clean but no joy when I put in batteries. I think it could be made to work again by someone with a little knowledge on this kind of stuff. Displays great on shelf though. Wingspan is 15 1/2" fuselage is 12" also the vertical tail is a little dented and moves a little bit. Thanks for looking and good luck
