The barrel and ejector rod have been changed, probably the extractor star too (the # behind the ext star if any, will reveal that) so the ext rod is mow a left hand thread if you ever need to remove it.
The serial # places the gun as shipped between 1917 and 1923. That makes it a 32 hand ejector - 3rd model, 5th change.
The numbers in the yoke are assembly #s, they never match the serial #. That's the wrong place to find the serial # on the yoke, it's in a different location on the yoke; see #3 location in my first post. You must look thru a chamber with a flashlight to see it.
Barrels are replaced because:
owner wanted the improved post WW II ramp front sight,
owner wanted a different length,
barrel bore was corroded/pitted,
or barrel had a bulge from a bullet lodged in the barrel.
The extractor rod had to be changed to fit the new barrel. And the ext star on the cyl had to be changed to match the left hand threads of the post war ext rod.
Sure it has value but only as a shooter, not a collector piece.
