That is a component/assembly data plate, one of many that were on each Me210 (and, in one form or another, on all Luftwaffe airplanes). Unfortunately, as far as I know, its entries do not include the main identification number of the particular airplane that carried it. Without that number (or detailed information on the plate's original acquisition), it is impossible to link it to a specific airplane and, perhaps, uncover service facts. Still a lovely plate . . .
