Dale,
There's no apparent eagle stamp on the rear cyl face in last photo, Post #1.
I didn't see one either, so I was curious as to if any of the eagle's head markings may still be present on the frame/yoke mating areas.
Not to poo poo on anything here but usually the silver medallion checkered grips, if numbered matching, are
typically found on "later" commercial framed revolvers with the squared off rear sight and will not have military markings.
Most of the more "immediate" post WWI commercial examples utilizing military frames/parts typically will have the checkered grips without medallions.
While the OP has stated the barrel has an eagle's head stamp I did not see one on the rear cylinder face, so I was curious as to if one was really there and if I couldn't see it, and as to whether or not there were eagle's head markings on the frame, especially in the yoke/frame mating area.
Nothing is impossible and curiosity was getting the better of me with regards to the grip s/n and frame military/inspector markings.
In this s/n range I guess anything is possible with regards to expected parts/markings, etc...
Once again, just curiosity getting the better of me and nothing meant to be a detractor to the OP's fine example.
More overall pics would certainly be appreciated.
Dale
