Hello, This is the Gunzs Sanyo Pz IV f1/f2 kit. It is a rebox of the high tech kit now all in plastic. I would like to trade this for a Trumperter KV 1 kit. I need to keep the trade in the US due to shipping cost. Both sides pay their own shipping. Kit is open but all parts are sealed in their bags. The box says Mr Hobby on it but I was told it is the Gunze kit. You can e-mail me with any questions. Thank you Brock.
