Jumo 211 Engine Plate?

Was delving in my piles of old military junk and rediscovered this. Bought about 25 years ago at North Weald or Old Warden. Sold as being a plate off a Jumo 211 engine – taken from a wrecked Ju88 in Norway IIRC. (It came with a certificate giving the details, but it’s buried somewhere else)

Is this correct? Amongst the numbers there seems to be a ‘211’. Could someone post a picture of an uncorroded example in situ?

Thanks,
Mark
