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
