Question about my G grade

[Jack Johnson]

I acquired a G grade Parker a couple of years ago in a Horse Trade. I had wanted a vintage side by side for some time and grabbed this opportunity ( i now have three). The serial number on my G Grade is 91493 and was made in 1899. It also has fluid steel barrels with all serial numbers matching on the barrels, for end and stock. There is a repair code stamped on the barrels of ph3. Which I understand this to mean it went back to the Parker / Remington factory in 1936 or 37. Now, here is my question . I think this gun originally was fitted with Damascus barrels and later in 36 or 37 was refitted with fluid steel. If this is correct would the factory have kept the original barrels or as I think a former owner sold them. If anyone has a guess please chime in . Or better yet, if someone has a set of Damascus barrels with the above serial number please let me know. Thanks Jack
