The 380mm Wollensak Tele can be good and, in its coated version in particular, is lovely with color film. Infinity focus is about 9" and it fits onto a Technika board. Two minor caveats: Finding one in a good #4 Alphax shutter is not that easy; and you'd need to widen any lens opening in your Technika board past Copal#3 size AFAIK. Nice lens though. I use mine on 5x7". Probably because of this lens, I don't have anything in the 300mm FL neighbourhood anymore.
