Hmm....
Thanks for the link to Christy's thread too.
Firstly I have to say that is a lovely line up of smurfs there.
To me, the fake HK king does look very similar to the regular genuine ones but as you both say, the markings are not very clear. Maybe this is an older fake (such as the candycane HK fake) but in this case it is odd because the colours are more similar to the Spanish and CNT fakes.
Sorry, I have no more idea about this but I would like to say it is a lovely fake to have.
No worries, I make the pics a bit smaller.
