Vintage Code Practice Key / Buzzer For Sale:

Herald Electronics Co. Model SW-12 A
"Telegraph Key with Buzzer"

This is a very vintage unit. It is in its original
box, with the paper work, with an address of simply
"Chicago, Ill", with no zip code, and not even a zone.
I would guess 1950's vintage, but of course that is a guess.

The unit consists of a code key built into a base that
appears to be bakelite. The key is somewhat similar to
a J-38 (without a shorting bar), with shiny nickel plated
knurled nuts. The key has a regular knob, and not a navy
knob. Behind the key is a round cover over the buzzer,
and behind that is a place for a single D cell battery.

The unit is complete with the original instruction sheet,
in the original box. $40

Other Vintage items for sale:

Ameco Model BIU, SWR Bridge
This is apparently an older unit (1950's or 60's) that matches
much of the boatanchor gear, except this one looks very close
to new. Of course it works fine also.
The meter unit is in a very nice light gray / dark gray black
enclosure, with a remote sense unit which has copper plating
(still shiny). There are provisions for using a second remote
sensor and switching between the two. This sensor is model SWB,
and says it is good to 225 Mc. Of course it is for 50 ohm systems,
and has an SO-239 on each end of the sensor. $50

Vintage B & W model 426 low pass filter
B & W TVI filter, cuts off just above 10 meters, and will handle
1500 Watts. SO-239 connector on each end. This is an older model
that seems much heavier duty. It weighs almost twice as much as
the newer model, and looks like it would take more power. It
likely was made in the days that plate modulated AM was the
rule. $30

Johnson Nye Viking 250-20 Low Pass Filter
This is a 52 ohm cylindrical low pass filter with a cut off
frequency of 45 MHz and 75 db of attenuation. It is rated to
take 1000 Watts of AM, or 5000 Watts PEP SSB.  $35

Johnson Viking Phone Patch - Model 250-46
This phone patch is made to be mounted vertically beside the
rig. It is about 6 inches high, 2 inches wide and 3 inches deep.
It is possible that the face plate can be removed, and it made
to be mounted horizontally, but I have not done that.  The
reason I say this is that there are feet on the bottom, and on
the left side.  Maybe the feet on the left side are to protect
the rig. In any case, it has 3 pots on the front for Null,
Receive Volume, and transmit gain, along with a switch for
phone patch or microphone. On the back is a terminal strip
for speaker and phone line.  The microphone input has the 2
pin Amphenol connector like used by Johnson, Heath, Hallicrafters,
and many others in that era.
This one is in nice shape. Paint is original and nice and
lettering close to perfect.  No scratches that I can find.  $40
