Junkers 88 plate

Can anyone help me identify this plate please?

I would like to know where it was fitted and can you tell which actual plane it came from?

I tried to upload a picture but failed! Details are

Zeichn.Nr. 88.291-Z02
Typ u.Grp. Ju 88 A-1

It is alloy and measures 50mm x 70mm

Thanks, Terry (acclaim@hotmail.co.uk)
