The traces of the fourth survived OPEL Kapitän Hebmüller have been recently found in Russia. In the 1980's the car belonged to a young lady-surgeon, and participated in a number of oldtimer shows in the USSR. That time the convertible changed its original cherry body colour to white. Though it has not been showing up since 1989, we have grounds to believe that the car is still alive. Many thanks to our friend Igor for the informations! Follow the upates!
