That's interesting, I didn't know about these trusted authorities. Here are the IPs:

    $ curl -s https://gitweb.torproject.org/tor.git/plain/src/or/config.c | grep -Eo "([0-9]{1,3}\.){3}[0-9]{1,3}:" config.c | sed 's/://'
    128.31.0.39
    86.59.21.38
    194.109.206.212
    82.94.251.203
    131.188.40.189
    193.23.244.244
    208.83.223.34
    171.25.193.9
    154.35.32.5
    199.254.238.52

I get the same country list as you:

    $ cat ips | xargs -I% curl -s http://ipinfo.io/%/country | paste - ips | sort
    AT  86.59.21.38
    DE  131.188.40.189
    DE  193.23.244.244
    NL  194.109.206.212
    NL  82.94.251.203
    SE  171.25.193.9
    US  128.31.0.39
    US  154.35.32.5
    US  199.254.238.52
    US  208.83.223.34

And here are the organizations they're associated with:
