For some reason, they are not listed in the website
www.specialforcesroh.com, that has many names of SIS/SOE/SAS agents among other "special units" (like commandoes and paratroops).
A memorial commemorates Sentzen:

Both men left Norway during the Lofoten raid in March 1941 to join the Allied side. Sentzen is said to have sailed with a fishing boat to Norway in 1942 to establish a radio station but it was bombed.
