I hacked Peter Karbe video when He was holding and reading and video camera was scanning Max Berek Notebook ,1922 50mm Lens Design Data.

 

You can read each element design data , distances , glass details and many more details.

 

Here is the pdf file. If you put it in lens design software , wavefront analysis , simulate , its better.

First vertical row lists glass surface number

Second row is the radiuses either negative or positive or infinity.

Third row is about distances and thicknesses on one horizontal axis.

Fourth row is glass numbers as well is the right end last raw is alternated glass numbers.

Fifth row is abbe numbers.

 

I dont have any idea about all other numbers.
