Could it be there were no NAPCO badges until 55.2 or later. People just slapping them on because they look good. I would think the installation instruction manual would show the badge and where to mount it with dimensions, if badges came in the kit. Maybe someone has a legit installation manual for AD era Napco kit.
These Napco emblems sure look like they have been on there a long time & it does not appear that they had any specific location to mount them, nor do they appear to have any evidence of ever being painted red.
