The original plan was to rebuild a rusted and tarnished 5625B rotor with parts from my 5606 parts collection. I assumed the difference between the LM and KS56 rotors was purely cosmetic.... not the case. For some reason, I haven't completely figured out yet, the KS56 movements need more clearance so the bearing is taller. The LM rotor will hit bridge plate if installed. Anyhow, The only NOS 56KS rotor I can find is 40$ plus 18$ shipping which makes my eyes water. I could use the whole rotor if anyone has one or just the KS56 barring if anyone has one that has tarnished weight. The bearing on my current example is totally shot - half the teeth are missing from rust.

509564 - ideally
509574 - i think will work too
