Building on a 2022 post about finding a copy of the long lost Slovenian OS/2 Warp 4 - https://www.os2museum.com/wp/slovenian-os-2-warp-4/ - some fellow software archaeologists have concluded some other localization editions are still missing - copied from the post's comments:
-- OBattler says: December 8, 2024 at 9:53 am It turns out Slovenian isn’t the only version missing of OS/2 Warp 4.0 – Portuguese (Portugal) and Portuguese (Brazil) are also missing, as are Dutch, French, Finnish, Norwegian, and Swedish, and a non-trial version of Hungarian.
OBattler says: December 8, 2024 at 10:01 am I just found FixPack 5 for OS/2 Warp 3.0 (or at least, references thereof) Arabic, French (Canada), Hebrew, Thai, Turkish, and, apparently, also Bulgarian and Lithuaian! So OS/2 Warp 4.0 must have also existed in these languages.

Anyone who can help find these CDs and help the os2museum.com preserve them (and optionally upload them to archive.org, too) is very welcome to join our cause.
Also looking for any (ex)IBM employees thst worked on the OS/2 localization projects and can help with this!
