Thank you very much for that video as it was very helpful and enabled me to realize the pendulum spring is broken. I want to fix it myself but not sure if I need a 21-6 or 307. It was purchased new in 1977/78. I see numbers that say 94 cm (over) the numbers 66.00 I also see a 451-050 above that. I'm going to try and measure the size of the broken spring but was wondering if you might know. Thanks again for the video and the help.
Thanks for the great video, I have a Haller AG 14cm 178, i think that type of leader would do it, could you confirm this, also bought a Enfield mantel clock with Westminster chime and when it arrived by post the leader was missing, I have a picture of it the seller sent me. There seems to have be a pinion pin on it just below where the suspension spring and another one down at the end above the weight, any suggestions what to replace it with.
