For sure. It's not a "heavy metal" though, mind you. The stuff is very pliable - like some kind of aluminium composite. Would only heat it from the back side if I were to attempt it, but will probably just leave it. Yeah, right! lol I'll get this sucka back to 100% straightness and sell it on ePay as some kind of long lost NOS masterpiece. lol
Heat will not help at all! Don't get a heat gun near it! You'll be able to get it right again, with care. Just make sure you don't stretch it.
I have seen one of the early metal badges, with only the ball on it - didn't say AMIGA. Maybe that one was for a 1000 keyboard?
