I have a SAA .45 Colt, that I have verified with Colt as a being a 1st generation that was received by the Government of 24 December 1884. The sn check by phone ($150.00) dis not tell me anything about why this weapon has a 4 6/8" barrel, and is shown in the records as having been a 7.5" originaly as issued. The weapon has a E in three locations; left side just above the large screw small E, just below set screw for the base pin a large E, and a large E on butt below strap screw. Inside loading gate is two digit "10" so I am certain along with the SN 113812 this is a 1st Generation. I have pic but not sure how to post as this is my first time on this forum. Any help would be graet. Thanks
