Subject: Submarine Hunley Binocular Information

Message Detail:
Dear Mr. Eisenhuth:

Welcome to our discussion board and back on active duty. Your project sounds exciting, especially whenever you can have the opportunity to inspire high school scholars.

We have seen published x-ray images of the Submarine HUNLEY'S hand-held signal lantern. This type of lamp was a common item at the time. Various names were used to describe it"

* Dark Light
* Boat Lamp
* Picket Lamp (usually fitted with a vertical ring for a wax candle instead of burning fluid pot)
* Police/Watchman's Lantern
* Signal Lantern

... and yes, even:

* Flash Light

I'm not certain, from memory, if the term Bull's Eye was in general use at the time, however, it may have been.

With regards to Blue Lights, which, upon investigation, you will readily discover are quite different than signal lamps, and radiate with much more brilliance and visible at distances of from ten to fifteen miles, you may wish to consult:

A COURSE OF INSTRUCTION in ORDNANCE AND GUNNERY;
COMPILED FOR THE USE OF THE CADETS of the UNITED STATES MILITARY ACADEMY. by CAPT. J. G. BENTON, ORD. DEPT.,
LATE. INSTRUCTOR of ORDNANCE... 1862

... using the link provided below.

As to your quest for a marine glass, a.k.a. binoculars, you may wish to contact Malcolm Addoms an antique optics dealer who dwells in the City of Richmond.

Two final questions:

1. May I ask what you used to replicate the glass blob lens of your lantern?

2. Are you looking to use a marine glass similar to the pair found on the HUNLEY or a possible larger set which may have been used at Fort Moultrie and could have been similar to what Professor Thaddeus Lowe might have carried aloft during a number of his balloon ascensions?

Best Regards & Much Success,
Walt
