There are two more diagrams of this fuze. (attached)
The source of the diagrams is a drawer in the basement of the Military University in Brno.
There is an unpublished textbook on mechanical time fuzes (undated, but before 1968). The author passed away in 1970.
The textbook lacks pictures, but the text describes this fuze matching the numbers. The designation of the fuze given by the textbook is " J.L.935".
No mention on the country of origin.
Any info is welcome.
Thanks, Bob.

The author of the script, unknown to us as of yet, used the illustrations and text for the prepared teaching material. Where was it from - I guess it is of French origin (according to the shape of the threaded part in the shell ). What course or training was this material for - ammunition specialization? .The fact is that the Czechoslovak Republic was a country where high soldiers from Egypt were trained (including anti-aircraft defense) from the level of platoon commanders to the chiefs of the state's air defense, directly in the Czechoslovak Republic or in Egypt. Among other things, Czechoslovakia was at the beginning of the Military Technical University in Egypt (professors from the military college from Brno taught there).
Based on the type of material in the drawings, I assume that it must have been some kind of higher technical education. What is also worth mentioning is the prefix "Fig". ,, is special for the Czech environment and is used only and only in the Czech patent literature..

Sorry my bad, the author is Ladislav Lošek.
He was born in Lomec on February 16th 1927.
He graduated the Military Academy in Brno in 1955.
Unlike the undated typewritten text mentioned above, there is also a hand written text dated July 1st 1961 describing the fuze J.L.935 as French. (found out today)
For a DIXI fuze mentioned in previous chapter he gives the source: Mémorial de l'artillerie francaise year 1940 Band 1 No.73 (maybe a trace?)
In 1964 he held a rank of major and completed his "aspirant paper for specialisation exam" named "the calculation of the spring drive of mechanical time fuzes"
The same year, he wrote a paper on the use of piezoelectric cuts in the fuze construction.
In 1967 he is already a Lt.Col and writes a teaching aid Fuzes Design Part 02 - Mechanical timing fuzes at MTC in Cairo. (mentions J.L935 - see attached pics)
In 1968 the textbook Zapalovače 1 (Fuzes 1) is published. Written by Lt.Col Lošek and Lt.Col Grexa. Published by the Mulitary Academy in Brno. (no mention of J.L.935)

I have no information on his textbook Mechanical Time Fuzes published by the Military Academy. ( A different textbook with this name was written years later by different author.) Parts of the typewritten text are included in the later published Fuzes 1 Textbook.

I almost forgot to thank phil12 for writing the post for me.
Thank You, phil12!
Bob.
 
Interesting connections ....
a) in the scripts published by Bob, I found that for the J.L.935 fuse , the authors used an earlier work by a Polish author, i.e. from May 1939.W I A D O M O Ś C I TECHNICAL ARMS AND Q W A R T A L N I K W Y D A W A N Y P R Z E Z DEPARTMENT OF ARMS OF THE M.S. ARMY, i.e.
Czesław Ostaszkiewicz, Zasady construcije i dokładność zapalników zapalnikówmechanicznych (zegarowych) page 288-
b) the initials J.L 935 are the initials of the French engineer and designer Jean Lasserr. No. 935 since 1935 . (it matches that US patent application...)
