Thanks for posting! The part you have here is a coil balance assembly. Yours appears to be a match for the Series 210 Roller-Tilt balance, but you'll need to be sure to compare the specifications to confirm this will be a fit. If so, you'll need the S210-05.

The compatible pivot bars and coil brackets can be found tagged below this thread.
