Hey Bob122515, good to hear from you, I wanted to respond to your question just so you know we are here, please try and put up some photos, they always help. I am a bit confused about what your referring to when you say @Bob122515 wrote:
spring drum
I am assuming you mean the mainspring barrel, but I am not exactly sure on what parts your referring to. Most likely there may be a few things to keep in mind when setting this back up but I am not completely familiar with this movement. Remember that photos during dis-assembly are very helpful in assembly. Looking forward to see what you have going on there. Have fun, William
