Can't find right keyboard layout, looks like Qwerty with french numeral/diacritic layout above it

This keyboard is non-standard, someone has modified a French keyboard to make it partly English qwerty. There's no input source that will fit it from Apple, but you can make one with

Are you sure the previous owner did not give you a copy of a custom input source that he must have used himself?

Any way to get a refund?

You might want to check Apple > About this Mac > Overview and see what that says about the machine. Also System Report > Hardware Overview.

Sorry, don't know about the availability of keys.

It certainly is odd. Could the previous owner tell you where he got it from? The only qwerty French keyboard Apple makes is Canadian French, which is a lot different than either French or Belgian.

You should be fine with US or ABC or US International PC (if you want the special deadkeys for accents in the last one) for touch typing.

PS The keys are probably original, just moved around.

Looking more closely, I think I see two keys which are on yours but not on Belgian French as far as I know...
