I have an Avus 6x9 (dial-set) with serious haze in the air space between the first two groups. This group is cemented into a barrel that screws out of the shutter with no easy way to access the internal surfaces. Any idea how to service this or is it beyond the realm of the amateur? Do later unit focusing skopars also have this problem? Are unit focusing zeiss tessars constructed the same way? I've been passing up a few nice 9x12s as servicing the shutter has not been a problem for me but I'm stymied by that lens.
