Dan,
Originally I posted pictures of this gun before the recent firing pin work was done. So...the screw under the lever was correctly timed and the other screws on the locks were also adjusted when this work was done. The overall fit is not that great, there are still gaps between the locks and the frame. My guess is that little to no real hand fitting was being done in 1947 on the Field Grades.
Overall, still a nice little feather weight with ejectors, for what I paid for it. Once I find out about the lock numbers I will provide an update.
Here are current pictures of the screws (sorry about that!):
