The Zeiss lenses in barrel for LF are likely to be either pre-WWII or CZJ lenses. Arne Croell wrote a two part article on the CZJ lenses for _View Camera_. They made a very neat looking fast wide angle lens called the "Lamegon" of recent vintage.
West German Zeiss made some excellent fast lenses for 4x5". I have the 135/3.5 Planar, which is outstandingly sharp, fast and smooth, though coverage isn't so wide--it's designed mainly for use at wide apertures with a rangefinder, when camera movements aren't as important. They also made a 75mm Biogon and a 240mm Sonnar, and there was a comparable set for 6x9 (53mm Biogon, 100/2.8 Planar, 180mm Sonnar). The 4x5 set was for Linhof (usually Technika and Aero Technika), and the 6x9 set you can find for Linhof Technika 23 (and maybe some of the Linhof 220's) and Graflex XL.
They also made a late run of the 135/3.5 Planar with T* coating of about 100 lenses aimed at Japanese collectors. These usually sell for over $2000, and I think Kerry Thalmann has owned and sold two of them on eBay.
