Quick update on this, the lens wasnt glued at all. Just bezel set I to the case like a cabochon stone... I'm assuming that means it's never been replaced.
Anyway, removing it took about 30 seconds. I have the new lug made and ready to solder on (just need to get everyone out of the house for a while so I can work in secret).
I was also able to straighten the bent crown. Things are coming together nicely. I just wish I had more time to work on it!
OH: I'm not sure I ever got the pivots seated. I am going to try once again and will check end shake and make certain the pivots are in the jewels. I have attempted to seat the pallet at least 10 time today. what's that saying about doing the same thing over and over . . .
A quick look at the parts catalogue sheet on Cousins suggests that your spring isn’t quite the right shape which will always make the guesswork harder. Cousins has them in stock at only £2.20 so worth getting a replacement.
The installation is a little unusual, but the Google drive link in this thread has a pretty good image
There is also a suggestion in that thread that the barrel arbours might not both be the same. Worth a check they are in the right places.
