  Thanks,,
    Our cam was fitted with a high grade Ziess lens that cost a fortune even
 then, 
Zeiss made a lot of lenses, some of which were great.
Goerz made a few of the greatest lenses ever made.
For personal use, I'm looking for Leitz Summicron in all focal lengths,
and Nikkor 105mm that was made in mid 1960s.
And, if I can ever get a 4x5 digital back, I want a Goerz Dagor.
All out of my price range.
