You are right about where the let down was. There was a hole in the plate somewhere near the stem. You would be able to let down spring if you knew that in advance. After plate was removed it was pretty obvious, little too late for me. There were a few other parts I haven’t seen in the form this movement presented. There is a little spring, almost arrowhead shaped, that a small gear sets on that engages winding mechanism. It just sits in a slot on the main plate and the gear that sit ontop has a bit of room to move around a bit. Little tricky if you don’t see it ahead of time. Also another similar small piece under auto plate that is pushed by a spring to act as a ratchet type device there. At first I thought that might be a problem but I just put everything in place, put on plate then there was an opening which allowed me to take a screwdriver and set the spring in position. Biggest issue I have is I haven’t got anything to work on this weekend. I do have an old South Bend 18 sz 331 but I haven’t found parts for it yet. Needs a balance complete, the staff is broken and wheel is very rusty. It needs a set lever as the thumbnail hook has rusted off and a dial wouldn’t hurt either.
