It's an awesome vintage Tamiya model kit 1/35 scale of the German Tiger 1 Tank Military Miniatures Series.
This particular rare early model is number MM156-800, which is from 1975, made in Japan.
This comes complete and in excellent condition for its age with contents still sealed, decals & manuals untoched. The box does show signs of wear due to age & storage but overall in excellent condition as well.
Please see all photos carefully as they form an important part of the description.
