Never heard of this before Al but it bears a resemblance to a story that I do know of - a well known micro owner of many years had the only surviving Bruetsch Bussard in storage , broken backed and possibly beyond economical repair , at that time . The glass windscreen was stored separately . Something similar occurred here and the car was believed to be lost which is how the screen came to be , very kindly ,donated to my Pfeil , 4 wheel version of the same car itself having lost its screen . Does this sound like the same story to you ?
