Hi I was wondering if someone can shed some light on this German built tandem. The only thing which is non-original are the 144’s and the horn. The original front wheel is a Sachs drop center with a large drum brake. The rear it had was a Durex single speed coaster brake. I have removed the wheels in favour of the 144’s. It has telescopic front forks and this is the original paint job. Weight as equipped is 78 pounds. The frame is super heavy and has a wild amount of flex over uneven ground. Please help me to id this strange monster. I would love to know more about
