Pilot House Door, RH / Ship's Bell

Pilot house door on SC 93. G.S. Dole Collection. 
Note the ship's bell above the doorway. At least two different styles of bells were used on chasers. See the item showing the LH pilot house door (SC 354) for another style example. Ship's bells of cast iron puported to be from submarine chasers have appeared for sale online; however the example photos suggest that the chaser bells were bronze, not iron. The door opens on the right side, hinges on the left. This seems to be the most common configuration, but not the only one. The shot of the door on SC 354 shows hinges on the right.
