Here is my Nightowl. Before this sale, it was the only one. But now there will be more ppl who can join the Nightowl club.
There was a question about Depth Black, and Depth Black is the only black for skulls. There are other names for black used for Clacks, but they are so rare that I have never seen one (and I have seen a lot of Clacks). There was Sinter Black, Pasties Black, Exxxon Black, and Stardust Black. However, some Clack collectors have told me that there was only one color black ever made, even though it was called different names. But only CC can confirm this for sure. I don't know of any other blacks.
On Nightowl, the eyes are Revenge Red. It is part of the "Bloodshot Series", the other members if the series are Mr. Friday, Terminator, Sacrifice (not shown), and if there are other members of the series, they are unknown to me. AFAIK, Salute and OG Tricolor are not part of the Bloodshot Series.
