Looks like a modified version of Belgian french layout to me... The shifted numbers are the only real difference that I can see..
In case you are interested, it's very much possible to use a different layout in the system than the one printed on the keys. For example I use both Finnish and English US layouts on all my keyboards, whether they are actually Finnish layout or not. In Windows I switch with Alt-Shift between them. I prefer the symbol placement on English, but often have to use Finnish characters ä and ö when writing emails for instance.
For touch-typing you don't even need to look at what is printed on the keys (although I can't actually touch type myself).
