Howdy, I have never had this problem but I was just thinking about it. if you dont mind I have a thought 🙄 did you put some kind of oil and let it soak in for awhile??? also wondering if a little heat on the hour hand bushing, like with a solder iron, or coarse you do not want to burn or melt anything 😯 . JUST me thinking. be careful, have fun and I hope you get it!!!! William
