In reading several post from Feb 1, through Feb 6, 2008 I found information very close to information on a gun I have. The gun was supposedly acquired in Pearl Harbour by an artilleryman stationed at Scoffield Barracks on that infamous day. The gun is a Colt 38 Officers Special, Heavy Barrel (cross before and after heavy barrel on the second line only.) Top of barrel is marked, Colt PTFA MFG Co. Hartford, Ct. U.S.A. Patd Aug 5 1884, July 4, 1905, Oct. 5, 1926. The barrel is 6" with a slight taper. Front sight has a vertical adjustment. Rear sight has windage adjustment. Matte finish on sight ramp in front of rear sight with 5 groves (adjustment marks) in front of the rear sight. Walnut checkered grips. Rear strap, hammer, cyclinder release, trigger, checkered. Silver Colt medallion on grips. Blue steel. Serial # is 643813 and it appears to be y stamped below the frame # but no Y anywhere else. Information sought is for sentimental reasons. Information on the 2008 post suggested that gun was built in 1937. This is a little later serial number. Not a Target Model. Thanks for any information.
