SPECIAL NOTE ABOUT LABELS AND DATING:
The dates on Japanese key labels give the date in the reign of a specific emperor. For instance, 9640a shows the date as "Showa 19 years, 9 months". This is the 19th. year and the 9th. month of the reign of the Showa Emperor. Showa was the formal regnant title of the Emperor we know as Hirohito which was his personal name. (Thanks to Edwin Lowe, VK2VEL for this information.)

9650 CAPTURED MINIATURE JAPANESE KEYS:(14KB)
This small key was brought back by a 24th Division Signal Company
officer, Ed Shakalis (KD1BJ), who removed it from a captured Japanese
command car in which it was being used on the Philippine island of
Mindanao during WWII. The key is enclosed in a black plastic cover
and slides into a lead-weighted base that was screwed to a shelf on
the back of the front seat of the command car. Another similar key is

Brought back from the Pacific Theatre after WWII. This key has both
open and closed circuits. It is plated brass on a black base mounted
on a metal bracket. It is enclosed in the original wooden box with
a sliding wooden cover which was apparently mounted to a radio or
table by metal brackets which are part of the box. The writing on
the bottom of the box says "electric button" in Japanese.
9665 JAPANESE WWII NAVY KEY:
This key is very similar to the boxed key shown above. The difference,
however is that this key carries a label written in Japanese and mounted
on the metal base directly under the lever.

9672 * JJ-38 JAPANESE COPY OF A J-38 WORLD WAR II UNITED
STATES MILITARY KEY:(21KB)
At first glance, this key appears to be a standard World War II vintage J-38
United States Military Key. However, it is marked JJ-38 and the key mechanism
is the familiar imported Japanese design with the ball-bearings at the end of
the trunnion that has been widely distributed in this country since the
9674 JJ-45 JAPANESE COPY OF A J-45 WORLD WAR II
UNITED STATES MILITARY CLIP-ON-THE-LEG KEY:(21KB)
At first glance, this key appears to be a standard World War II vintage J-45
United States Military Clip-on-the-leg Key that was widely used in mobile
communications applications. However, it is marked JJ-45 and it carries a
complex metal label written in Japanese where the American J-45 simply carries
the 'J-45' stamped into the metal leg clip. Scott Hill, K6IX has the only
other known example of this key but it simply has a large 'JJ-45' stamped on
the side of the leg clip and no label. Tetsuo Yamamoto, JA3PYC, has
translated the label as follows:
Leg Clip Key JJ-45
Parts Number 0390-0011-0000
Serial Number (Blank)
TOHO DENKI KABUSHIKIGAISHA (TOHO Electric Company Ltd.)
(Toho Electric Co. is now Panasonic Communications Co. Ltd. Toho was a facsimile maker and joined the Matsushita Group ((Panasonic)) in 1962.)
Tetsuo also tells me that the Cherry Blossom mark at the top of the label is
used by the Japanese 'Self-Defense Force' (Army) and it shows that the key was
made after WW-2 with license from the Signal Corps. He does not know what the
letter 'S' inside the Cherry Blossom stands for but he has seen the letters
'Q' and 'W' inside the Cherry Blossom and sent me an example of the Cherry
Blossom 'W' mark stamped on the side of a pistol.
In addition, the actual key itself is marked JJ-37 in raised characters cast
into the base in exactly the same place as the common American J-37 key.
Another example of the JJ-37 key owned by Scott Hill, K6IX, has the words
'Soling Japan' moulded into the bottom of the base but this one does not carry
that mark. It is unclear when this key was made. This key was origianlly
found by Bill Gallier, W4WX who took these photos before I bought the key.
