O/S upgrade

[longshanks]

Hi,
I am looking to revive my old Dell laptop a Latitude i5 with 32 bit architecture, at the moment It has an older Mint 19 OS but after coming across a recent article on Sparky I want to give it a go. My Q is What version of Sparky to use obviously it got to be 32 bit version but I cannot find.
many thanks
Brian
