IBM - The illusive Yugoslavian layout

Hello everyone.
This is my first time posting here, and I am very excited to discuss all things keyboard with all of you!
Anyway, to stay on topic, ever since I started watching Chyros' videos I always wanted a Model M. Now, in my search for one, I found some had a Yugoslavian layout, which would suit me perfectly. And, as luck would have it, last summer I tracked one down. However, this sent me into one of the deepest rabbit holes I have ever been in. That being the search for Yugoslavian layout IBM keyboards. According to most sources, only Ms were available with it, however, I found some long dead listings for blue switch Fs bearing the YU layout. I also dug up some spec sheets which indicated that IBM also offered YU layout 4704s, however, these have yet to be confirmed to exist.
Now, I am starting this thread so if anyone finds any Yugoslavian layout IBM keyboards (not counting IBM's later rubber dome keyboards) you can post them here. Another layout that would be nice to see is the Serbian/Cyrillic layout (not to be confused with Russian/Cyrillic) as I have yet to see B/S keyboards with that layout. I am hoping that will help determine how rare/common these keyboards are, and maybe we could even find some undocumented ones!
Thank you for taking the time to read this.
Until next time,
Jugostran

I've never seen this layout
Picture for reference. Good luck mate!

It does not escape notice that the alphas in this layout are all identical to the then-regular
YU layout, with the
{} key being the only exception (instead of a
Ž key), even though both characters ARE in the tertiarly layer, in their expected places. I'm tempted to think the
{} key was required to be there for some mainframe software packages, but that makes little sense — perhaps the
Ž key was omitted because it wasn't supported in whatever charset was being used... or, perhaps even, was left out by
mistake.

I assume the omission of the Ž key is a mistake, as you mentioned. Other than that the alpha cluster looks identical to my YU M. However, since it is a terminal board, we never can be sure about the other keys. One way to confirm is to find a YU Terminal M or F. However, I have yet to stumble upon one that wasn't just a keycap swap job.

That strenghtens my hyphotesis. Unless we find evidence to the contrary, we should assume the {} key in the first diagram is a mistake.

This is huge. 3179 terminal keyboard is an F122. This basically confirms that IBM had at least assigned a part number for a Yugoslavian layout F122. Now, same as with the F107, it is really hard to get concrete evidence with no keyboards being found in the wild. And that is coming from someone who lives in the region.
Luckily I have a contact closely associated with the Croatian branch of IBM. They told me that some of their coworkers use Ms that they found in storage. I am hopeful that there are some terminal boards, and maybe even an F122 in their storage.
Also, this indicates to me that P/N 1393669 (standard for all IBM and Lexmark YU Ms) might have also included a square badge variant (in addition to a gray badge, blue badge with and without SDL).
EDIT:
Could I get the source document for these layout descriptions? I would love to find out which P/N these keyboards used.

No way, that is brilliant. If only I could find one of those. I can imagine that they are basically keyboard unobtanium though.

YU is actually quite a common M layout. You could also get them (well Wheelwriters) in YU Cyrillic

I have found 10-15 Ms (including M122s) with YU layout.
So not that common, but it is a thing.
And wheelwriters? Yeah, those are common as typewriters were the main form of data input up to the late 80s in the region.
However, we are still yet to find three specific boards:
YU F122
YU F107
YU Beamspring
If anyone has any leads/works somewhere with IBM keyboards stored away, please get in touch!

I found a pretty interesting specimen. This seems to be a Type II M 122 key terminal keyboard. Part number is 0985955, made in the Netherlands.
This thing makes me hopeful for the existence of YU F 122 key terminal boards.

Im confused lol
So are you looking to find a yu layout f just to have the pn? I think those are in the datasheets
The only thing unique about a yu latout is the alpha block and they can be put on any m or f

Am I understanding it correctly that you are looking for an F YU?

I am looking for a YU F122/F107 or beamer.
The F107 has a P/N for the YU layout. The F122 currently does not (another poster on this thread just found some datasheets showing the layout). Same for the beamer.

Well, I haven't found any new YU P/Ns of note. But, as I stated before, I still believe that YU Models F weren't ever manufactured. Instead, you got a keycap set to swap out the UK/US ones. In light of this, I present to you my YU IBM Model F122 (1385082)!

You'd do well adding pictures to the wiki so the evidences you find don't get lost. Threads here don't last forever, I've lost count of the number of wiki references pointing to DT threads that became dead.
