The Vivitar is a Vivitar designed lens and produced by Komine(s/n. 28xxxx), there is also a Kino produced version(s/n.22xxxx). Not sure where you made the Cosina link 🤔 The Takumar is obviously a bit better but also 3 to 4 times more expensive 😉
Why the hell do you care so much about the serial numbers on these lenses? Are you afraid someone is gonna steal that lens number and use it in some nefarious way? Its a bit silly and pointless to hide that number.
