That's DarrylD. He's here on Pelican. He used to spend a lot of time on the board but not so much anymore.
The restoration of his 912 was really spectacular.
It's amazing how a guy can do so much time consuming work (auto restoration) and still find the time to completely document it along the way. He set the bar way high for the DIYer crowd.
Here's his home page. It has all of his cars listed with links.
