This auction consists of three A. W. Bowman & Co (of Boston, MA) crystal receiver parts: detector, #14 condenser, and the Boston Tuner coil. The board is oak, measuring 11.5" x 13.5". It appears old, but I do not know if it was part of an original crystal set or not. The tuner coil measures 4" x 4" x 10 5/8". The hard rubber 4" x 4" ends are slightly warped. One slider has a missing knob. Nothing has been tested electronically. Overall weight is about 6 pounds.
