Enlarging Lens resource needed

I need some info on some enlarging Lenses
Most seems very old

Schneider Kreuznach componon and componar
50mm/4.0
75mm/ (4.5) I think
80mm/5.6
Wau, thats at lot of blades in a diaphragm

Rodenstock Rodagon
50mm/2.8 (compared to El-nikor)

One called something like cassar 50mm/4.5-f/8.0
(mounted on a Liesegang enlarger)

Items where given to me from a closed down photoclub
Info, links and comments are welcome
Regards Søren

For the Scheinder lenses just go to the Scheinder website. Odds are they'll either be under the new section or if they are old the vintage section.

Søren, the USA Schneider site has the vintage information, the German site has all the pdf's.
