I am puzzled by Bristol boast about making tubular steel aeroplanes, when this one is clearly constructed with a hardwood frame. Is the photograph a modern one reproduced in B&W? Does the machine still exist? For it is a good quality image for an 'old' photo. Was the result of the "experiment" the Bristol Bulldog fighter? Is the quoted (1920's) correct, as the framework suggests 1910-1920.
