Nice mid 60's Partner K-14!
I probably have a clutch for it. Lol .. Is It yours? The pulley looks like It might be a bit too large In diameter. It could overspeed the blade.
No worries though; if you got hit by desentigrating blade pieces and knocked out; I'm sure the belt would grab your hair on the way down. Good news though; it probably doesn't idle well because it's pulling the wheel at idle too,~ (what's left of it after exploding and your hair), since there's no clutch.
That is the belt guard they used too. (Not one)
