Playart Thunderstrike 035 Submarine. Automatic diving and resurfacing. The submarine is complete and working. It is lovely condition. The 035 sticker is showing wear. These submarines never had the Thunderstrike sticker shown on the box. I should know as I had a couple in the early seventies. Powered by a Penlite AA battery in a detachable 'torpedo' motor. The box is showing wear , but it has protected the toy for over 45 years. It has lovely graphics depicting a WWII convoy. Approximately 13 inches in length.
