I have tried numerous sources but I cannot find the purpose or utilization of the following part. I found this part among the many various parts I had stored previously, but had not properly labeled. Any and all assistance will be appreciated.

A sticker on it has the name bruse and the number 681-60228 followed by the MB Symbol then the name Mercedes Benz.

There is a black and a white wire (coming from it/going to it?) on end cap and it appears as though a mechanical "shaft" my attach at the center of that same end cap. It is cylindrical in shape with an aluminum center and each end cap is a dark brown heavy plastic.

Someone has applied a whiteout on it with the letters MBZ which leads me to believe that this is a used part yet I have no recollection of purchasing this item.

Sorry, that is all I know. I have no clue what it is, what it does or what chassis of Benz it is for.

Thanks,
Dave H...
