Description

Vintage electronic 4x4 toy truck lot Mean Machine Soma for parts partially works. There are 3 trucks here more or less.
1. Soma truck: slow speed 2 wheel drive works. 4 wheel drive does not(fast speed). 1 of the wires connecting light detached so light does not currently work. It can probably be fixed with a little soldering.
2 second soma comes in parts. It was used to replace one of the gears in other truck. For parts only.
3. Mean machine: spring in bottom of battery compartment broke off so I put a little aluminum foil in bottom to complete connection just to see if works. Foil is lying in there loose and easily falls out. Lights come on, motor runs but it is not catching gears so it won't currently work in any of the 4 gears. Someone may be able to fix (probably not any easy task though)
