Not sure, what it is, some kind of key ring, looking at the address is is in Australia, which makes sense as my bus is an import. Tried to google King's Tyre & Brake, but nothing comes it - it's probably very old and they may have shut up shop years ago.
Try this Here it is http://www.yelp.com/search?cflt=tires&find_loc=Shailer Park Queensland, Australia I googled the town and number thinking it might be a phone number. This link shows a map of the town. Number four is in loganholme and number one is just down the road and has the same phone number ? Then this link is for the Tyre company and the second address listed looks like the right on. http://www.beaurepaires.com.au/store-locator/?address=Loganholme
Brilliant, I wonder what the 4812 number means/meant Might give em a call and see if they have any history
