Slant 6 Pak?

I wanna say it is an Offy manifold that uses 3 side draft webbers. I see them in Ebay and at swapmeets every now and then.

Although it's not 3 deuces, I am starting to put together a triple SU (3 single SU sidedraft carbs) together. Might be a real pain in the kazoo to get set up right, but it would be real eye candy on a slant. Couple of guys on an Aussie forum have them and looks pretty awesome.
