General Information
The BA 220 (CS-57) are the long version of the BA 200 (CS-49), the CS numbers correspond to the maximum reach.
These were the original EX brakes, these became the 7100's and later the 7200's. There appear to be only minor tweaks
between models. The instruction sheet was dated Apr 1979.
