Chaser bridge wing. G.S. Dole Collection. This is a scan of a photo negative, showing the starboard bridge wing of a chaser and the detail of the stanchions and deck planking. Note the machine gun mounted on the bridge wing, and the rudder cable cover on the deck. The distortion below the bridge wing deck on the left and the over-exposure on the upper right are defects in the negative.
