The scan here is from a seller, Heinz Preller in Baringhausen from the year 1990.
The left column includes the lens designs: Flektagon, Biometar, Sonnar, Prakticar. The next column is first the maxiumum aperture followed by the focal lenth. The column labeled Blende means aperture, and denotes automatic or stop down aperture. The column Linsen/Glieder is Elements/Groups. Gewicht is weight in grams. Minimum Entfernung is closest focus in meters. Minimum Blende is smallest aperture. Filtergewinde is filter size. Bildwinkel is angle of view. And perhaps most interesting is the entsprechend bei KB - or small format equivelent.
The bottom is a special lens, a category unto itself. It's a Spiegelobjektiv (Mirror Lens) focal length 1m (one meter, or 1000mm) f5.6 made of four elements and two mirrors weighing in at 14kg (ca. 35lbs!)
For those of us who's first language is English, you might notice some interesting tidbits about how photo stuff is different in German. For one, the use of commas replaces periods when used in numbers: where we'd refer to an aperture of f5.6 they call it 5,6. Another oddity is that Zeiss is written Zeiß. I was taught that whenever a word in German ended in two S's they were replaced with the SZ or Scharfes S. But I've always seen Zeiss ending in two S's.
And on the Zeiss topic- the lenses are noted as Zeiss Jena, those were made in the GDR (German Democratic Republic.) The factory was split up and there were two companies called Zeiss, one in the East (the original,) and another that was made from employees who fled the Soviet zone and founded Zeiss in Oberkochen in the west.
