Remington NM Army-Additional Markings
I have a NM Army revolver, SN 92010, that has the additional markings "A5315" stamped on the underside of the barrel just prior to the SN and the number "5" just after the SN. These letters/numbers appear hand stamped and are not as uniform as the serial numbers. On the bottom steel strap of the butt are stamped (?) three small letters "USN". Can anyone provide information as to these additional markings? I would also like to know the approximate date of manufacture of this pistol. Some additional information: There is the inspector's letter "A" on the trigger guard and evidence of cartouches (the oval outline) on both grips.
