The actual height of the exposed glass on all lenses is 7 inches.

I have both mast lights from the Cambria (aka E.H Hunley) and the port and starboard lights. All are 16 inches high. All are original.

Is the lens 16 inches high or is it the entire lamp? Is there a make on it? Perko seems to be the main lamp supplier of that period.

I have both mast lights from the Cambria (aka E.H Hunley) and the port and starboard lights. All are 16 inches high. All are original.

Those are for towing. Old Great Lakes Rule 4(a) required "two white lights in a vertical line one over the other not less than six feet apart." Those were the days when consort barges were common.

The lights I remember seeing from that time frame were kerosene lamps.

Looking for the rough size, type, and examples of the mast lights on the ships built at AmShip in that time frame. There seems to be two of them placed in conjunction with one another and appears to be at least 24 inches in height. I have attached the Gilchrist boats as they seem to offer the sharpest pictures of the lights. I have highlighted the two on the Hydrus picture. Any help on this matter is greatly appreciated.
