The JJ-38

The JJ-38 looks a lot like a J-38 from a distance, but close inspection shows a very different key. The base is marked JJ-38 in the front and has no eye screw. The key itself is a very common Japanese model with a hollow cast brass frame and ball bearing trunnion pivots.

Notice the conical circuit closing switch knob and the unusual arrangement of the lock nuts on the trunnion supports.


In this picture you can see the unusual shape of the anvil support.

Here is a JJ-38 in the original box. There is no indication of the manufacturer. (This key is now in the collection of Dave Johnson, N0MNO.)
