A part of the object is missing (photo front: left). I assume that the find was originally symmetrical and that a disc with a rivet hole and the small edge projections have broken off. The middle disc and the edge projections are only drilled into, but a second rivet would be necessary for stable fixation.

Could VT-YJ888I8N be part of a trim stretcher? Came as a suggestion for identification.
