This is a Robertson head screw. It was a common screw head on boats back in the day. But we don’t see a bunch of them on Chris Crafts from the 1950’s So why is it on the Tarp Find Cobra? TOMORROW we break the news. No more teasing, because this little screw head confirmed 100% what we had thought. We did not want to divulge any of this until we could defend the crap storm of internet opinions until we could defend it. So tune into tomorrow for the big reveal.
