John, not to be a complete wet blanket or anything, but since your lens' coverage won't allow much in the way of movements and since you have it in a shutter, loveable or not, why not put it on a humble Crown Graphic? And if you want shutter speeds faster than 1/50 to take advantage of the lens' speed, why not a humble Speed Graphic?

Yes, I know, too obvious. But, y'know, I swear I've seen an image of a 44/5.6 Super Aviogon on a Speed somewhere on the web. I've dandled one of those lenses on my knee, it lives the next town over. What a monster! If a Speed is good enough for that Bertele design, its good enough for yours.

Cheers,

Dan
