 # 24 .....Morse telegraph key, Air Ministry. (RAF Type D)

The RAF Type D key is a classic straight key which has now become a collectors item. It is also, however, a lovely key to use for morse operating.
Is a solidly made British morse key of WW II era, commonly known as an RAF (Royal Air Force) Type D morse key. It has very heavy duty square silver contacts with the lower contact mounted on a leaf spring, so that it can move slightly under pressure. It also has contacts at the rear end of the moving arm, so that the key can be used to open or close a circuit when depressed.
The labelling on top of the cover reads KEY MORSE TYPE D REF NO 10A/7373. It is marked with the "Air Ministry" AM and the Crown.
This key was offered by CT1BY.

 

 # 25 ..... MFJ Deluxe morse Code Practice Oscillator

Model MFJ-557
Volume control adjusts from barely audible to blaring full sound. Tone control gives you a wide adjustment from high "squeaky" to low "booming" tones. You even get an earphone jack for private listening. You can plug in an external speaker.
Oscillator runs on a 9 volt battery.
Purchased a few years ago,  in Portugal at "MFJ" dealer in OPORTO.

 

 # 26 ..... ???

Missing information about the manufacturer and the nationality of this key.
It was taken of from one old and abandoned fish-vessel here at my home town.

 

 # 27 .....ORIGINAL D.B.G.M. MORSE KEY

Original JUNKER key mounted on a strong bakelite base.
The original "Junkers" were the militaristic land-owning aristocracy of Prussia in the early 1800s and the name has become something of a "power name," used in English to refer to "landed aristocracy."  This aristocratic key, however, was invented by Joseph Junker, a German Naval Radio Officer in World War I.
Electrically the key has three connections, with matching silver contacts at the rear so that the key can be used for make/break keying as well as the more usual on/off keying. 
In other words, the contacts at the rear will be held closed (for a receiver muting circuit, etc.) until the key is pressed, opening the rear contacts and closing the front ones a millisecond or so later.  Simple but foolproof T/R switching, with built-in QSK!
Above the knob it shows the letters:
J.JUNKER
HONNEF / Rh.
D. B. G. M.
The key is very well preserved and has a very smooth toutch and nice work.
Purchased in Lisbon, during one ham equipement show and trade, a few years ago.

 

 # 28 .....US Navy Military FLAMEPROF MorsE Key

This is a flameproof used US Navy Morse code telegraph key type CTE-26003A in very nice condition manufactured by "Telephonics Corp". NY, USA. It's design was apparently copied from the German Luftwaffe Key.
This key belonged to zs6ccl because it shows a blue tape stuck onto its wooden base.
I don't know when it came to Portugal but was purchased in Lisbon, to the old owner CT1EFG, ex-ZS6CCL

 # 29 ..... HAM KEY HK-3

I purchased this Ham key in August of 1981,during my stay in Mundelein, Ilinois, at WB9RCY 's home for MARAC Convention at DesMoines, Iowa.
Years later it was placed on a granite base, cut and polished for the purpose. At the back face a hole was made to pass the wire.
I think it's a beatiful piece and a very nice working cw key.

 

 # 30 .....New Zealand morse telegraph key WT-8 AMP

This is a morse telegraph key model WT-8 amp No2.
WT-8 keys were made in over 100 versions in 6 countries and in huje quantities since 1920. Used by British armed forces during World War II.
However, this key is very hard to find because it's the version made in New Zealand and numbered. The metal plate under the knob says:
" KEY PLUG
ASSEMBLIES
Nº 25      N.Z. "
All the metal parts are brass which has a black oxide finish, the key is marked 'NZ' with a broad arrow on the leftside of the arm, near by the knob.
The lever arm has also the letters "ALKIN" as somekind of a stick.
This version of the WT8 is very rare and I never saw another one for sale.
Purchased in Lisbon in a junk store.
