Paracette or Paraset research again

In the Netherlands we have the 80th year of freedom celebration after the second world war on the 5th of May. In honour of our freedom I have written some posts that are follow ups from posts I wrote in the past. If you like to read it, here are the links:

Paraset

The case of the "Paracette". Unknown if there was a Paraset among the 5 transmitters (receivers) that were used by the "Zwaantje" resistance group till September 1943. Known are a Soto transmitter, a Winchester transmitter, an Eton-3 transmitter, an Eton-4 transmitter and a homemade transmitter. So far I could not find anything about these. It can be that the name Paraset was not really known and instead they gave the tranceivers names so one or more of the above could be a Paraset after all.

PA3BCBs note

Unfortunately Gerard PA3BCB died last year. He was the one that rescued the WW2 Paraset instructions and gave them to me. Well you know the story, and if you don't, read the articles about it on my blog. Gerards widow brought me a note he wrote for me before he died, he was obviously busy to find out about the transmitters that had been received by the "Zwaantje" resistance group via the Sweden route. The note was about some facts he did read in the report that "Ton" van Schendel wrote after the war. This report can be found at the excellent site from Willem PH0WAW. A very nice network overview block diagram from "Zwaantje" can be found here. It contains some faults but it brought me closer to an answer.

I decided to read this report again and this is what I found about the "de Soto" transmitter.

It turned out that an espionage group in Delfzijl, which as it turned out later was led by "ZWAANTJE" (Dr. Oosterhuis) and which maintained an intensive traffic with England via Sweden, had received a transmitting and receiving device from England (mid-February 1943). This equipment was equipped with four crystals (a day crystal with evasive frequency and a night crystal, also with evasive frequency; the day wave was about 47 and the night wave at plus minus 85 meters)

Further in the report some other facts about "de Soto"

Later it turned out that the initial failure of the connection was not so much due to the low power of "DE SOTO" transmitter, but rather to the lesser ability to operate the receiver. The whole case, transmitter-receiver plus P.S.A. (power supply) was no bigger than a cigar box and could easily be carried in a briefcase. Due to the extremely complicated construction, the receiver had a fairly small tuning scale, while the range was quite large, namely from about 25 to almost 100 meters. The coordination was therefore very difficult and critical and required great skill. We have taken great pleasure in such receivers by making some belt spreading and the use of a long rod for tuning, which made it much "finer", especially when most of the receivers had to be put away as a result of the surrender order (13 May 1943).

At first I though "a cigar box"? In my opinion that is too small for a Paraset. But looking at the above photograph I'm not that sure anymore... the suitcase on the pic is very small considering the size of the handle. I don't know the size of a cigarbox at that time?  However the Paraset on the picture is believed not the exact model that was described. There were several models made, and not every model was build into a suitcase like in the picture. So what the "de Soto" transceiver looked like will remain a mystery.

In my opinion it is very likely that the other "transmitters" were in fact "transceivers". And except for the homemade transmitter(s) the transceivers with names could actually be all Parasets.
