I've never seen this exact horn anywhere in my collector car travels. This should be the exact make and model of Northeaster horn for the 30-31 models. It even has the box it comes in which you should preserve in a airtight glass case. Not cheap, but if you need that final authentic touch.ebay item #392609569309
