hi all.presently working on a AS 1171 of which there seems to little info e.g part nos etc.i seem to have had a accident with one of the train wheels.(please see pics)still new to this hobby so sometimes struggle to identify certain parts unless i have a makers chart in front of me.can anybody help with this and have any chance of finding a part without having to source a whole movement (there are some on e-bay) which would not make economic sense?B.

Hello, I've been struggling for two evenings now to fit the train bridge on this ETA 2832. Every time it looks like all pivots are aligned through the jewel holes and I begin tightening the bridge, the wheels begin locking up. On closer examination, it looks to me like the 4th wheel is not seating flush against the centre tube as shown in one of my photos. I believe this because the pinion on the 4th wheel is higher than that of the escape wheel, and equally about the same measurement out between the 4th wheel and the 3rd wheel pinion, which is lower. It also looks like the 4th wheel is fouling under the train bridge. In your opinion, would my suspicion be correct or should the 4th wheel's pinion rest approx. 1 to 1.5mm above the flange of the centre tube. If it should be flush, do you have any tips to seating it as such? I have obviously tried carefully wriggling it under light pressure without luck. I've added an extra photo showing the placed wheels during disassembly to give some context. Thanks in advance
