Acquired this data plate - supposedly from a JU-87 Stuka
Some details include:
Title: Vorsch ift für Nachtanken
Google Translate doesn't like "Vorsch" - but this appears to be a refueling/lubricant plate. Engine perhaps?
It looks like you have a placard for listing capacities of fuel (Kraftstoff) and oil (Schmierstoff). Beyond that, I can't say where the placard is from or even if it is off a Ju87.
