Ball Perfect Mason with # under Mason??

[Lo-Retta]

Found a Ball Perfect Mason jar. Under Mason it has the #7. #7 is also on the bottom of the jar. I have looked up many jars and I can’t find any that show a number under mason. It this a replica? Also the “Perfect” came out in 13-22 but the “Ball” logo came after 23 , right? The second bottle has Ball on the bottom. Can anyone tell what kind of bottle this might have been used for or how old?
Thanks
