is this rep copy or phantasy?
edit:
ok, this is gen, rep is not phantasy ! Challenge 48 Black Flag, limited edition of 100 pieces
Some things are off in rep, but if price is not high I will still thinking to buy one :)Needs custom PVD work for frame and crown, repaint+ relume hands, rest is as usually - more or less.
