@Findecanor: true — depending on how you interpret it, it could be something like an APC Clicker keyboard, which more closely fits the "moulded" aspect of the description, but I don't think they have a sub-frame either ..... though that's also open to misunderstanding in the same way that it doesn't have NKRO.
Pretty sure whatever it is, it's not worth buying, let's put it that way : )
Also is it possible to change the keys from french layout to qwerty.
Only works with keyboards where all the keys are the same profile. Not the case here, so, no.
