I have in my collection such a bike, built in Germany in 1950. It somehow found its way to the states, though the circumstances remain a mystery. The history of my bike is known back to 1972 when a friend and former BMW dealer owned it. There have been five owners since. Below are some pictures of the bike over the years.

I was recently contacted by the son of a former owner of my motorcycle who has shared some interesting history and photos. I am awaiting more details, but will attach one of the photos that has been shared with me.
