Nice selection!
Is is possible to see the leaves of you gratrixianum var. gratrixianum?
According to the type sheet, they should at least be 4 cm broad....

Me too, me too! 🤗

It's always difficult to judge the size from photos without measures or something known to compare with, but might your callosum be of the local variety (var. sublaeve), Werner?
Yes, probably sublaeve. This means they should be from south of Thailand , Thai growers call them SOUTHERN FROG CHIN .
But there seem to be different forms again.
Paphiopedilum callosum
Thats why I stopped using variety names unless being absolutely sure.

Herbert ,
I checked , the leaves are 3.5cm . A plant of a friend from the same batch has up to 5cm.
I named it gratrix gratrix because the reliable Thai grower did so.
Got a few more plants with either very narrow leaves or broader ones.

I dont believe too much in this kind of nomenclature , sometimes based on a singl plant only.
To know the origin/habitat would make more sense, but does not work after breeding.

Thats life !
