These are 3 sections of the death star model (I edited the COA to prevent copy): 1 large and 2 small. I cleaned the oxydation with white vinegar and a cuetip (worked like a charm, green is gone). the movie prop vault got it from the screenused company (now closed).
I'm in the process of framing them (with photo of georges lucas and the model, a plaque and a star wars vintage white patch), quite hard to choose the layout.
