This photo of the GPO Number 15 Morse Key is of the bottom side showing all the interconnections. This is one key I really didn't want to disassemble, hi..
The key shown here is the Marconi Wireless Telegraph Co. Ltd London serial number 444. A good solid Morse key with a condenser in the base for contact spark suppression. Interesting the cutout area on the top of the lever just like the large Marconi spark key shown down below. The ivory ID badge on the rear of the key base came out around 1905 to 1907.
And here is another view of the number 444 key.
This is a side view of the fairly large Marconi spark key from the time just before the 1912 Titanic disaster. Interesting that one like it was used in the wireless room of the Carpathia by the operator Harold Cottham. In spite of the size it works very well with an excellent "feel" to it after proper adjustments.
I think the two smaller terminals near the larger ones at the rear were for receiver muting during key-down conditions. The wood base is about 9 inches long by 5 inches wide.
Shown in this photo is the newly received very nice 1920 to 1922 time period(I think) J.H. Bunnell "Gold Bug" semi-auto Morse key. After some adjustment and contacts cleaning it works great. Missed one in 1979, so here in December 2011 finally got one.
Here is a nice old Australian Automorse key from Adelaide around 1918 to 1920. An interesting key for sure, and after careful adjustments can be real nice to use. There is a paddle for auto dots, manual dashes, and auto dashes. Seems like the base needs a re-plating with fresh application of nickel. Originally the whole key came with a nickel plating. Received in February 2012.
