Trumpet with SS Banner 49x 49cm

[Waffen55]

Maybe I can get some thoughts on this item in my collection.
The trumpet seems to be from C.Rinkel. a wind instrument producer from Strassburg. I found another object in the national germanic museum in Nürnberg. Germanischen Nationalmuseum Nurnberg | Objektkatalog

As for the banner the materials used seem to be high-end. The banner is identical on both sides.
