Here is the add from CF. After re reading and looking at the original photos, I have no doubt it is the original finish. Well taken care of obviously. Looks great for a 50 yr old firearm.
First year production Python, 2 1/2 inch blue. Serial number 299XX, 1963. All original. The stocks are numbered to the gun. First year fit and finish is amazing. Overall condition of this gun is excellent. It had some rust under the stocks and very slight freckling under the trigger guard. It has a rubbed area on one portion the cylinder, possibly caused by sliding around in a box. Mechanically it is perfect. Trigger is glass smooth. Additional photos if needed.
