Here you go. Looks like your Mini was one of the last old style ones made right before the 580+ series was introduced.
Ruger has a chart on their website but it only shows when your Mini was made, no barrel twist info there.
Mods please make this a sticky at top pf page, so people don't keep asking it.

p.s. RJF already answered this for you in your "Picked up like new Mini 14 prefix 197 thread".

Your gun is a 1/9 twist. May be you should read your other post where RJF stated that for you.
