Hi Ron,
The side view photos and inside frame well photos look really promising. Lots of "in the white" surfaces down in the wells.
There are no "halos" on the barrel serial number. Depth of the barrel SN looks pretty shallow as well
Also...no "halos" on the 2-digit numbers on the extractor and the toggle link.
The partially cropped "9" on the chamber date had me worried as well.
I think parts of this gun may have had touch ups...other parts may still have their original finish.
Also...no impact or strike marks along the back of the frame where you usually see contact with the toggle train in its rear-most travel during firing :
