Very Old U.S. Wireless Key
This wireless key has heavy contacts and is nice to use. The old style base and terminals, etc. seem to place it during the early spark set days. However, there are no markings anywhere on the key or base to know who made it or when. Further research needed.
3 Excellent U.S. Morse Keys
The key on the left is the Navy key designed to take a flat spade plug from the cable of a semiautomatic key like Vibroplex, Mac, etc. The middle key is an excellent brass J.H.Bunnell and Co. New York U.S.A. brass key and is great to use. Also believe they called it the CQ Radio key in their catalog. The key on the right is the Signal Electric and Co. Menominee, Michigan brass key designed like those for radio use and railroad use. However, there is no shorting lever installed on this one.
WW1 FRENCH ARMY MORSE KEY
This is an interesting folding lever key from the top of a French army WW1 field set. Nice key from around 1917. The key weighs approximately 1 pound 7 ounces or just over 650mg or .65kg. The base measurements are 6 3/4inches(173mm)long by 4 inches(103mm)wide by 1/2 inch(14mm)thick. The brass lever length is about 6 1/2 inches(167mm)long. The original brass terminals labeled L1 and L2 were missing so I placed two nickel plated terminals there just to complete it. The knob seems to be a bone material which was used back then. There is a chip off one side of the top edge of the knob and the bottom edge. However, the key works fine and the lever can be folded. The front contacts are a heavier type, the rear seems to be just a resting point for the spacing adjust screw rather than contacts. Four of the smaller brass terminals numbered 1, 3, 5 and 6 were missing so I used some received from the UK. The French army WW1 field set shown in a photo is for reference only and was sold a couple years ago in Europe for 7,200 Euros on Ebay Germany.
