Well, finding info on pre-Borgward Hansas isn't easy, and I don't have any books on them. Sooo, it looks like the car is around a 1915 model if I had to guess by the picture. The only model designation I can find from that area is a 16-50 PS. I also found a Type E that seems like the sports model, but the name doesn't seem to jibe with the others I found.
