Yes, those are probably the last-mentioned transmitters in the following 
additional text from December 1947 QST:

"Other equipment...included a hand-cranked emergency set of the Gibson 
Girl type for 500 and 8280 kc., a special v.h.f. set for contacting 
aircraft, both provided by the U. S. War Department, and two of the 
famous British 3-16 Mc. Mark II transmitters (dropped by the hundreds in 
all occupied countries during the war)."

Kon-Tiki's call, by the way, was LI2B.

I didn't keep my own NC-173 very long; it was terrible for CW QSK using 
a separate receiving antenna.  Something in the front end would charge 
up in the presence of strong signals (i.e., from my own Heath DX-40) and 
take forever to discharge to the point where I could hear again.  I used 
to run semi-QSK on the traffic nets by switching the bandswitch to 
another band while transmitting!

One "wag" (whom I shall not name) replied privately to me that probably 
the Kon-Tiki team took the NC-173 along to do double duty as the raft's 
anchor!  That could well be, judging by Heyerdahl's frequent 
descriptions of techniques the crew devised to periodically remove salt 
water from the radio equipment to make it operational....
