I believe I have this identified right.... Most of you are going to be smarter than me on these.. Also I don't believe it has been refinished. The grain pattern to the finish and the crispness of the pony stamp make me think original. It does have light pitting in areas. Some scratches that look more recent. And thinning of finish/ finish wear of course. Pretty decent for a hundred year old slide.. The item "Colt 1911 Slide Assembly WWI 1913-1918" is in sale since Thursday, December 3, 2020.
