I am new to the forum and have some questions about a Remington 1903 that I have. I'm trying to find out exactly what its history is. Its serial number is in the 3120000 range. It has OG EK. On left side of stock and has the straight pinned stock. It is dated 5 of 42 on the barrel and is four grove and unfired with cosmoline still present. All of the parts that I can see are marked with the R. It has an original unused sling. It has other crouches present as well. Any help would be greatly appreciated. It has the ladder sight on it.
