Fundamentally sound example of scarce toys that survived WW-2.  This one was found with solid steel artillery wheels and came with electrical lights. I am not sure what is needed in the electrical system.  Axels and wheels rotate properly as they should.  Please use Ebay's Zoom to witness all legal description and condition.  I will gladly answer any questions.  I invite you to check out my other pre-war items.  Global shipping allowed.  Thanks
