When I get a vintage tool I start immediately looking for replacement part. After research it seemed e hardest part to replace is the garter spring for the articulating motor for the fan with a reliable substitute. I found a company that makes the springs and a stock item that is close. The major problems comes down to price break. Since small lots are considered prototype the first reasonable number is 10 @ $6 each. See below
