Many thanks to SWLing Post contributor Robert Yowell, who writes:

Hi Tom – some years ago, you posted an article about the famous Kon-Tiki expedition and the use of the National NC-173 on board.

Well, today during my first-ever visit to Oslo, Norway,  I stopped by the Kon-Tikki museum – devoted to the r expeditions of Thor Heyerdahl.

And sure enough, right there in the Kon-Tikki raft exhibit you can see the actual radio he used!  In fact, the radio operator was a radio operator named Knut Haugland, who was also a radio operator  for the Norwegian resistance during World War II. There is a photo in the museum of him operating the NC-173, which I am also including here.

If you are ever in Oslo, the museum is definitely worth a visit!

All the best,

Robert
