Here's something that perhaps is completely legit, but at a first glance looks bit suspicious to me.
I just (literally minutes ago) got a very interesting book 'Il potere nucleare delle Forze Armate Italiane (1954-1992)'
by Vincenzo Meleca.
And while browsing it, I noticed several familiar looking drawings.
Perhaps the Author got Enrr's permission (or even is
Enrr), but the fact that last of these drawings has credits removed, and there's no mention of Shipbucket in the index of sources (though this could be arguably pointless if
Enrr and author were the same person) made me somewhat suspicious.
