George, Do you have the subject parts now? Or are you trying to reproduce them? Do you know how may planet gears there are? Maybe they were trying to salvage the set by mixing the PA's and it could be the ring (being bronze) may have had excessive wear. They were probably trying to take up the backlash by using "thicker" toothed planets. If you were to make this today, you should use all the same Pitch and PA parts and relieve the tip and root areas to avoid interferences.
