Luxor, Barco and Emerson used the original case.
Barco has very different fonts on their badges so one can assume they made their own:

Apart from SABA, Nordmende, ITT and Luxor also had their own design on the second version units, Adman used the Channel F II case.
The SABA VideoPlay has the original controllers and pretty much the same board as the first Luxor version. SABA VideoPlay 2 has the second version of the circuitry on a full size board, much like some US machines that has the old case but the smaller PSU (and may or may not have an internal speaker).
The SABA VideoPlay 2 has almost exactly the same case as their first version (lid latch differs) and it has a small extra PCB to modulate the sound into the RF output channel, there's a spot for the speaker just like on the previous motherboard but none is mounted. Controllers are unfortunately the same as on the ITT Telematch, with a different knob.
The Nordmende is pretty cool, it has plain version 2 controllers with a silver sticker on top (matching the console but that often doesn't cover the original sticker). Case is pretty much the same as their Nordmende's Video Typer machine https://www.radiomuseum.org/r/nordmende_video_typer_laufschrift_generator_0500.html also found on http://atarionline.pl/forum/comments.php?DiscussionID=3851&page=2 (image below) Don't know which one of them came first but I'm guessing the video game came before the "Typer" as the latter doesn't seem to make use of the shape of the holders under the lid.

If you get super exited about the Video Typer, here's a pdf of service information that you don't need to google yourself:
