Vintage ADS 300 i/s Automotive High Fidelity 75W Speakers works bad tweeter

Description

Ok, so I have for sale a pair of Vintage A/D/S 300is component speaker set. I removed these from a old mercedes that I am currently restoring. I decided to remove them as there was some noise off the back left. Once removed I saw that bad tweeter.
Other notable thing about them whoever installed them hot glued fabric to the back on the magnets it mostly peels off and I took most of it off, but could be completely removed with some effort.
They do both function and have sound. To be honest I don't know much about them outside they were a cooler brand of audio when I was growing up.
They appear to have  removable plates, I believe the tweeter could be replaced. I am letting this go No Reserve Auction because I don't really know what they are worth and couldn't find much info on them. If you have any questions feel free to ask, I stride to be as up front as possible in my listing.
Edit: The blue on the back is not present on them. it's something happening with my camera and reflection.
