Chinese 105mm APFSDS ammunition

[Spaceinvader]

Hello everyone!
I am looking for information on the following 2 Chinese 105mm APFSDS cartridges. I have found multiple angles of them and after careful examination I believe I have both the bottom and middle sabots (as well as the 125mm sabots). What I cannot find out though is weather the middle cartridge is 100 or 105mm. I have seen it labeled as both and the sabots I have also measure 105mm.

The bottom most cartridge is a "DTW2" 105mm cartridge, same as the common Royal Ordnance L7 cannon.

I have also found another photo showing the same black semi-combustible casing(s) but the website I found it on was in Portuguese and google translate can only do so much. The article claims they are 125mm but that doesn't make sense.

Anyone have any other info regarding the middle black semi-combustible cartridge? Also any info regarding them would be greatly appreciated!

Well I have found more info but hasn't helped me at all figure out my original question!

The large black cases may be single piece 125mm rounds for a new Chinese 125mm gun, possibly for mounting on future tanks and not related as far as I can tell to other semi-combustible 105mm round. The black casings shown in the photo above are from the same display and can be seen in a few photos.
On top of that I found another photo of what also seems to be a single piece combustible 125mm APFSDS round, maybe someone knows about this one? Possibly related to the black cases above and the large tank cannon?

This isn't getting any easier!
