Your pictures are nice, but they do not provide sufficient detail for evaluation purposes. Although you may be spot on with the 95% condition, there are brownish reflections in the blue accompanied by swirl patterns, some corrosion on the hammer, and a lack of detail in the proof and inspector marks on the left side of the frame. The screw holes do look sharp, but the screw heads do show a couple of light marks.
Probably the biggest detractors are the lack of original box with label, archive letter, and original stocks. An original mint package will definitely be more appealing to collectors than just pieces of a package. And the fact that the Colt site does return the correct model for the serial number is good, but an archive letter is better.
Taking the pictures is a tedious job, but try to provide some more detailed pictures of other parts of the gun you missed like the cylinder face, top, bottom, rear, and front of the gun. And focus some of your pictures on places where there are roll stamps, proof or assembler marks, seams, or screw holes. The better you provide, the better we can evaluate.
As for an estimate, I'm going to say $4K due to lack of factory originality and questionability on some aspects of what I see in the photos provided earlier. Yes, it is a nice python, but is it a complete/original python?
