Was standing in front of it today and to be honest I didn't even notice. So perhaps the picture make the change more apparent. That being said based on the photos I'm thinking cleaned and re-finished versus replaced.
thanks for the day shots guys. so perhaps it was only re-coated with a different paint. but not simply cleaned. there was a mark in my photos that made me think the plaques were different but maybe it was dirt? I'll change the title.
