German accordion booklets (from 1924)

[Paulex75]

Dear Colleague, I am French (unfortunately I do not speak German) and I collect German postal stationary.
I have a question that has not yet been answered despite my research on the internet. My question concerns the making of German accordion booklets (from 1924), cards with paid answers that have serrate at the bottom of both parts. How many cards per booklet? Presence of heel (on the extremities)? Double card with only one of the two cards with serration (if ends without heel)? Thank you in advance for your help.

I can send you some photos to illustrate the question.

Best regards

Amha, il serait préférable de poser ces questions dans la catégorie „Deutsches Reich“ que dans celle-ci qui concerne les problèmes techniques de ce forum.
