The whole assembly was painted in a drab and unassuming grey, obscuring the seams between the wooden planks. In the center of each of the side walls there was a white circle with three stylized wings protruding from it -- the triskelion of the mythological pegasus Epona an Iomaghaoth, or at least an impression of it. And towards the front, again on each side, the word 'WHIRLWIND' was similarly stencilled.
