Well Ry, you really anticipated my dilemma. I had gotten the barrel, third, fourth, escape, and pallet out and was studying the second wheel up and down to try to guess if the friction fit (canon?) pinion comes off or the wheel comes off). I was going to post the question, but you beat me to it with the answer! I'm glad it's the canon pinion, since it would be hard to get any leverage on the wheel. Anyway thanks!
@Watchtime the crystals came in and look and fit great. Here's the one for the Empire. Thank you!
Looking forward to getting it back together!
