Thank you very much @Heliosurge, thats really helpfull I was already wondering why the MAS wouldn’t fit the Artisan. Will definitely have a look at the Guidebank as well as looking for posts from @Ludiks.
Actually my Artisan (used) came with the bare cheap strap but with the face comfort kit.
There is an install guide I believe posted there. You need to remove the face gasket and then the hinges to put the MAS on. Then reattach the face gasket.
