There is a small spring that holds the bars in place. Be sure its
OK. There was also a hammer assy sold with the plastic holders
& hammers. In the olden days when I was a kid we just ordered a
whole new hand unit as a rule. You can find plenty of hand units on e-bay
BUT a SC600 from different years may not work the same. Best way to
be sure is get the part # & look for one. The part # is in the
format of "S-#####".
Other problem with E-bay is the price !!!!
