Original Item: Only One Available. These were not "Officially" issued to soldiers: such luxuries had to be purchased privately by serving Officers. Simple but ingenious, these are spring loaded clip-on darkened lenses with a easy attachment system that can fit ANY telescope of the period with a rear eyepiece measuring from 1 - 1 1/2 inches across. So simple yet so effective.

The lens attachment comes in its original custom made leather stiff pouch with rich purple velvet lining. The snap is marked N.D.LTD with a patent number.

Well designed and beautifully made, ready for use or WW1 Display.
