You couldn't find anything on the internet about them?
Just and FYI...the realoem "code" is actually the 11 digit BMW part number. If you haven't typed something like
"BMW 63112359505" into a google search box (not sure why you wouldn't have, yet)...then give it a try. You should find some info (perhaps old) and images. If the part is still available...you'll also probably find vendors that sell (or used to sell) the part. And there's always eBay...perhaps you'll find a few items left if they are out of production.
Good luck...google is your friend in this case.
