The Rainbow is one of the primary models from BC. It's been around since nearly the beginning of the company. Logos are frequently changed, and sometimes the type of laminated wood. But the model remains one of BC's most popular. A distant cousin of the Hummingbird Trickster.
Pictured here is an unusual Rainbow. In November 2004, BC changed the logo on the Rainbow. The color is the standard Rainbow wood, but I discovered the previous Rainbow logo on the reverse. Two different logos on one Rainbow. The small print on the new logo reads "No. 52 Made in USA".
