Is your question about the button keyboards?
I've seen it referred to as Do2 or D-Griff (unsure on the reasoning of that name). Apparently popular in parts of Belgium. I think a search for Do2 will pop up some results here. In line with what Kimric said, it is a B-griff layout shifted by one row. There are 6 possible layouts for a CBA keyboard arranged by minor thirds in the rows. Those we call B and C-griff are the most popular, but at least a few of the 4 other layouts have been implemented.

I don’t have one handy at the moment, but the Roland Reference Manual for the FR-4x (and presumably the 8x) which covers piano and CBA models cites 6 right-hand layouts and has diagrams for each of the six. As I recall, the D-griff is one of those layouts in that manual.
The two accordions in the pictures are different.
The one on the right is Do2.
The one on the left just doesn't make sense to me.
Oh my, I hadn't noticed. Maybe the owner shifted the button caps in rows 1 and 4 for aesthetics?

It is the one to the left that is the problem. Never seen it before. Maybe he has moved the buttons, mut I do not think so
With the accordion on the left in one diagonal direction you have three white buttons in a row and in the other diagonal direction you have even four white buttons in a row. On a chromatic accordions you cannot have more than two white buttons in a row in the diagonal direction that you play. So this layout cannot correspond to any chromatic button system.

It looks like it could be related to an English concertina layout, though somewhat different. On the three outer rows, you would have the seven white notes in one group, with accidentals to the outside of those white notes. The inner two rows would make octave transitions easier. Maybe the extra white notes at the top end are like a short octave on an organ. That would make sense enough to me, though it's all just a guess. Strange layout!!
As Paul said, the black and white pattern on the left hand accordion doesn't seem to make sense.
On the other hand on a 5 row chromatic keyboard you'd expect rows four and five to match rows one and two. They do match when shifted "up" slightly, which suggests B-griff mechanism. So the black white pattern isn't purely decorative, but still doesn't make sense?

That's not an "odd duck" but a standard C-system accordion.

They both look like C-system to me, but how would I know?
