الن vs. ان لن

There are many false assertions about the King Fuʾād Edition:
that it is type printed ‒ it is type set, but offset printed
that it established Ḥafṣ ʿan ʿĀṣim as the most wide­spread read­ing
  ‒ the three gun powder empires, Ottoman, Timurid, Safa­vid ‒ and the Mame­lukes before ‒, did that,
    because for their non-Arabic elites that reading is the easiest,
    because closest to Standard Arabic
that it fixed the text once and for all ‒ in reality the oral text was fixed centuries ago,
the written text had minor variations, AS HAS the KFE and its descendants.
Here I will not write about the more than 600 changes that the 1952 edition brought in the qurʾānic text (including the sura title boxes), but just about one word in 73:20: /allan/.
This is not about /allan/ in general.
At most places it has a fixed spelling,
e.g. 18:48 الن

at 72:12 ان لن

just about 73:20 where we find a back and forth:
In 1924 (in the Giza print) we have لن in the first line

unchanged in the first small Būlāq print

changed in 1347/1928/9 ان لن

back in 1952 الن

the same in the small edition of 1955 الن

and in the small edition of 1962   ‒ الن

But in 1959: ان لن
(Havards holds all these editions ‒ Muḥammad Hozien took the pictures)

So far for real KFEs, which means
‒ published by the Government Press/Amiriyya
‒ no title page = [p.1] is completly empty
‒ an-nās on p. 827
‒ 12 lines per page
‒ catch word on each right page
‒ ǧuz, ḥizb, saǧada, sakta in cartouches on the margin
‒ text after an-nās with (simplified) abǧad pagination
‒ big format (27 x 19 cm) printed by the Survey of Egypt)¹ in Giza and after 1952 in šāriʿ al-labbūdīya 11, on the press of Dār al-Kutub
    small format (20 x 15 cm) printed by the Amiriyya itself in Būlāq
    (when a library has a 24 cm codex it is a cut and rebound big edition)
‒ no duʿāʾ ‒ a secular edition, by and for the state, not al-Azhar, as often claimed
‒ no eulogies after ʿUṯmān bn ʿAffān, ʿAlī bn Abī Ṭālib etc. in the information after the qurʾānic text
‒ no ribbon bookmark

Let's move on to "reprints" by private printers or foreign states.

Neither a reprint, nor a rearrangement of KFE set lines, but a reSet is the Hyderabad edition of 1938. It has been photomechanical reproduced in London (i.a. for Sharja), Islamabad, and Bairut (for the Libyan World Islamic Call Society).
See what the Indians did ‒ without extra nūn ‒,

London reprint for Sharjah:

what was made for the Libyans (squeezed in nūn):
