Attached is a photo of both the 520 (top) and 329 (bottom) movements. The 520 has the balance cock and balance from the 329 installed and is running great. The broken staff 520 balance cock and balance are installed in the 329. The upper bridges on the 520 have a cylindrically machined surface to fit the curves case.
