Rob, that "code" is actually just a standard copyright??I've seen many stories that originated in one country's comics reappearing in another country, with exactly that kind of local copyright added.
Anyway, it's definitely a Hubbard-drawn story. Without having the resources immediately on hand to know for sure, I suspect it's an edited version of W 10217 A-02 ("Guardian Angel"); the Inducks description seems to match, though this publication obviously drops the splash panel and some more material as well.
