Great, thank you! gpgsplit let me export and thus rebuild the packages
into a functioning state for my master and subkey keypairs.

I tried that and then modified the command a little bit (because I
figured I maybe can rebuild the entire keyrings):

I started, as in your example, with subpackets/000001-006.public_key and
then followed with just about all of the other packet-files:
   * I had to exclude pubpackets/000001-006.public_key because it caused
gpg to output the "no user ID" error.
   * I also excluded the pubpackets/0000*-014.public_subkey files and
their respective .sig files, because `gpg -K` then listed 'ssb' AND
'sub' entries, instead of just 'ssb' which I'm used to.

So now I have all the desired parts of my public and master keys, from
which I have been able export relevant secret subkeys to other machines
without running into the "no user ID" error message.

Thanks again Daniel!
