Zenit 3m Accesssory Shoe?

Has anyone seen one of these before? It came with a Zenit 3m I recently managed to get Looks like a flash shoe but it fits into the 3/8" tripod/ case socket under the camera.
Does anyone know if its a Zenit/KMZ accessory or something that some enterprising guy has made up? Any ideas would be appreciated, thanks

Just maybe they used nylon to take up extra unwanted threads in bolt. Or used to hold slave flash unit. Doesen't look like it is insulating anything. Don

If it was an official accessory probably would've had a KMZ or other factory markings on it...

No markings at all Vlad, looks like someone has made it up, maybe from other parts,but thanks for the input everyone
