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.) |
