They will have "MAHLE" on the underside of them iirc.
And no some are cast, early ones are forged
you should be able to tell by looking underneath the piston
a cast piston will have smoother and quite intricate shaped cant into it, whereas a forged piston will usually have sharper corners and a lack of deatil, as it has been machined

Yep thats how i was told what to look for.
think the forged mahles have 86p on the underside of the piston
