The story
W. C. Bramwell and his son C. C. Bramwell were able to gain experience with their own vehicle designs at the company Bramwell-Robinson-Automobile. After the falling out between Robinson and the Bramwells, the vehicle based on the Bramwell-Robinson Model B was to be produced as a revised version by the Springfield Automobile Company. The first vehicles were marketed as Springfield and later as Bramwell. The production was about three vehicles per week.
