Old Dealership Metal Tags

My Dart is very original and a big part of me wants to keep the dealership tag when it is repainted. Only problem is that it shows everyone of it's 4+ decades. The dealership is long gone, so it's not like I'm advertising for it and the car is an Albuquerque native. The tag adds to the ambiance, IMHO...

Anyone know of a shop that can refinish these, or is it something that a local chroming shop can take care of it - thoughts?
