Hi Vince,
This plate is from an aircraft airframe part because it has an "8" group number. The Vereinigte Deutsche Metallwerke AG (VDM) Company did specialise in aluminium alloy parts and aircraft propellers and systems. If this was from a propeller or propeller system, it would be a "9" group number (for aircraft engines/systems).
So this is from an aircraft part, probably an aluminium casting. The number 8-2056.22 would decode precisely to the part, but unfortunately I do not have the information to help with that, although I think it may be an undercarriage or wheel part. Note that the part number is identified as a "Sach Nr" or Item number, not as a Gerate Nr which is a device or complete piece of equipment. The Werk or serial number 61111 is quite high and so it is possibly a common part.
Notice the top Vereinigte Deutsche Metallwerke AG Frankfurt Heddernheim is the parent company, but the lower Hersteller, Vereinigte Deutsche Metallwerke AG (the maker) is
the secondary VDM factory at Hildesheim just south of Hannover.
