Welcome To Page 10 With Some Marconi Keys

AN OLD MARCONI TYPE 100 MORSE KEY

Here is a very old Marconi Morse Key Type 100 on a bakelite base which is mounted on a wood frame which is mounted on a steel plate. There are both front and rear contacts. There is no maker's label with the type number or a serial number on this key. The key comes approximately from the 1919 to 1922 time period as the same type can be seen in photos of Marconi's yacht Elettra wireless room. One photo in 1919 and one in 1922. Received from England October 2007. This is a nice operating key with a good solid feel to it and heavy contacts. The photo below was in the ebay auction showing another old Marconi key possibly Type 100A, 111A or similar. Presently in need of some cleaning up overall, and replace the missing front upper contacts set and adjusting screw with locking knurled nut. An old stock list or catalog lists a Marconi key Type 111A as a "Key, Transmitting with back contacts for operation of a 1/4 KW set from ship's mains". See also Morsum Magnificat MM75 page 45-6 info. May 2009.....

Another photo of the 111A(100A?)key after receiveing it, facing left before cleaning up.

And yet another photo of the 111A(100A?) key facing right before cleaning up.

Here is the first photo of the 111A(100A?)key cleaned up a bit with plunger for rear contacts added(was missing or broken off)made from Chinese chopstick. A 6mm screw for front contacts upper set, and the hard wood base cleaned up with old gray paint removed. Sanded and waxed.

This photo shows the 111A(100A?) key between an actual Type 100 on the left and a Type 365 on the right for comparison.

Here is a view from the left side of the three keys together.

And finally a view of the rear of all three keys.
