Yes, the body was manufactured by Eisenbahn Verkehrsmittel AG. Primarily, rail vehicles were manufactured here (freight wagons; especially tank cars; passenger wagons and railcars). In the 1920s, tipper bodies for trucks were also produced for a short time, so-called "EVA-WOODS". Two points for pulling the puzzle out of the black hole. I will therefore leave out the year of construction 1928.
