part from Volga

Hello All! There is a subject. Moreover, from GAZ-21. New. This is a disk with springs, and 2 rings that seem to be made of PCB. Here is a photo of this - http://2065.nm.ru/f/volga.jpg (152kb) Perhaps this has something to do with the axle shaft - the hole in this disk is the same as axle tip. Does anyone know what this is called? PS In general, I would like to sell... maybe someone needs it Best regards, Evgeniy.
