Secret Communications 3


Impression of the


of the Exhibition held


16 November 2019


Status: 18 November 2019





Rudolf Staritz's first visit to our museum premises; and me

We particularly prepared for him a special seat and desk where he can sit more relax and discuss matters on: mainly manual coding methods known to him; but he speaks, of course, from his great background experience.

The seat is a must - considering his age of  becoming next month 98 years old!



A most impressive view on a line of six enigma's

Where else in the world, has this been realised?

Roughly: from front to the rear:

build in 1926; next 1928; mid 1930s Enigma type I Army version; GAF type of 1944; the submarine type M4; and at the far end type K once made for the Swiss Army.



 Rudolf Staritz looking at the most rare SG 41 nick-name: "Hitler Mühle"

Please notice: he told me once:  that when he was engaged at : "Nikolaiken" (Atlas) in 1944; he operated lines executing actually: SG 41 machines!

The uniqueness, is, that this device does not belong to the regular's collection; though isn't ours either!



Rudolf Staritz looking at the two "Fialka" machines, which can be demonstrated - as an operating system; thus two machines communicating to one another



Another impressive view; in front: the SG 41 "Hitler Mülhe"



Two German  HAMs in discussion with Rudolf Staritz



Willi is studying the descriptions

In (full) front the 1928 type, the forerunner of the Type G machine.



Paul is programming  (setting up) a Spendex 50 telephone system; of which two sets are actually operational for this occasion

Each set needs, nevertheless, a set-up information.

Please notice: that the early 1980s digital data processing (Spendex 50) considered from its speech reproduction does not in favour of the "scrambler techniques" of 1940 - 1960s. Maybe - in regard to data security! But in respect to audibility, it was definitely inferior, still!

Infront the box of a most rare 1980s "Pocket Telex" type PX 1000". 



Great: Tatjana J. van Vark building up her unique apparatus display, which will be demonstrated and explained later this day

Please notice:

this was the only occasion during the entire Secret Communications 3 event - that she will display and lecture her magnificent devices!



All Tatjana's created marvellous gear is clearly explained; but may never be touched without wearing special gloves



Gerard and Paul in discussion



Hans Goulooze in discussion

On the left the Fialkas.



Raymond's lively explanations attracted most of the day quite some people

I suppose, emphasised, because he explains from his own commitments - in this intriguing "Texlight Pocket Telex" project.   



 Without further explanation

Nail and his American friends, in front Hans Gouloose.

Still, Rob is apparently intrigued by Tatjana's explanations.



Robert looking at the NRP search HF/DF set "PAM 1000" (100 kHz - 1000 MHz), once used by the Dutch "Radio Controle Dienst" hunting for illicit transmissions

The specifications were spectacular: 100 kHz up to 1000 MHz within 1 dB accuracy!




 Again - Raymond telling about the history of the "Pocket Telex"




Where ever can you come so close to Enigma's on display, elsewhere in the world?

What likely counts, is, that the visitors aren't comparable with the regular museum visitors elsewhere; but still unique it is.



Rob's penchant is for a great deal dedicated to mechanics



Rudolf Staritz explains, that when for him the wartime came to a closure, for example, the Korfu receiver of late 1944, on the far left-hand side, wasn't known to him at all

He also showed great admiration in the BZA1 Ju 88 mechanical bombing computer.

For more detailed photos: BZA1



Raymond is still explaining about the "Pocket Telex" type PX 1000 

But from his first class acknowledgement:  as he was partially engaged in its development.



A great feature of our exhibition, is, that most of the time - visitors are in discussion, or looking at demonstrations



No comments



Still dedicated



Rudolf's desk was full of manual coding-instruction materials



The rarity of the SG 41 "Hitler Mühle" is apparent

The second Spendex 50 telephone in between the SG 41 "Hitler Mühle" and the Hagelin M 209



Towards the end of the afternoon, Dick was released from his kitchen supervision, and he used the opportunity to take a look at Tatjana's magnificent techniques

Please notice her wearing white gloves.



Paul is explaining  to Nail the different types of "bugs" from various origin, on display



Just before the closing of the exhibition



The Enigmas being packet for transportation, as no valuables will be left outside exhibition hours 



The clearing preparations are nearly accomplished, and the lights maybe switched off - and the door closed; the plastic boxes waiting for transportation
