K-W Coil

 

These old coils are really neat items to have around from a past era of amateur radio history among others. This one was manufactured by the K-W company.

These coils were produced by many different companies including the  Jefferson Electric Company

The photograph on the left is of the points and vibrator section of the coil. The photograph on the right is of the top.

  

  

  

In these next two photographs both the left and right sides of the K-W coil are shown.

  

  

  

Unlike the Jefferson Electric Company Coil, the K-W company choose to put their logo on the bottom. Notice the ink stamp underneath the round K-W logo. It proudly states "Made in U.S.A.". This is a marking that is sadly becoming extinct.

  

  

  

The photograph on the left is a close side view up of the points and clicker. The photograph on the right is a close up of the bar that is on the top of the points in the picture on the left. This metal bar has the K-W makers logo stamped on it as well as a patent date of 1914 which is the same year that WWI started. The U.S. did not enter the war until 3 years later in 1917.
