VINTAGE Marx Toy TWA Battery Operated Jet Plane Large Model MADE IN JAPAN-RARE

This is a large jet toy, measuring almost 20 inches long and 17.5 inches wide.  I have not tested this, for the life of me I cannot figure out how to open the battery compartment.  This is being sold as UNTESTED and SOLD AS-IS, NO RETURNS FOR ANY REASON.

This does exhibit wear from play use and storage.  There is some corrosion to some of the metal.  One of the engine thrusters looks to have been repaired at some point.  (this is pictured).
