Came across something today that baffled me. A 1957 vintage Python, serial number 44XX, with what looked to me like a standard polished blue finish except that the insides of the cylinder flutes appeared to be bead blasted satin, like on an early fifties Officer's Model or 3-5-7 with the "Dual-Tone" finish. The first thought that occurred to me was that somebody had dropped a 3-5-7 cylinder into a Python, but the serial on the cylinder matched the one on the frame. Second thought was Python barrel on a 3-5-7 frame, but it was definitely a Python frame. The underside of the trigger guard was polished. Only the cylinder flutes had this bead blasting, resembling the bead blasting on top of the barrel and frame. Has anyone ever seen anything like this?
