Why This Pistol Matters
Serial number 369379 is historically important because it represents a WWI-era Colt M1911 that remained in U.S. military service long enough to receive Ogden Arsenal processing. That makes it a useful bridge between early M1911 production, military service life, arsenal rebuild programs, and modern CMP release.
For the 1911 Database, this pistol is valuable as a CMP-documented Colt OG rebuild reference. It helps collectors understand how legitimate arsenal rebuilds can retain important original Colt features while showing official military refurbishment marks.

Research Notes
Research method: This record separates CMP-documented observations from collector conclusions. The OG stamp changes the classification from factory-original condition to official military arsenal rebuild history.
The current assessment is based on the CMP data sheet and owner-submitted notes describing a Colt frame, Colt slide, Colt barrel, Eagle Head S14 inspection mark, OG rebuild stamp, walnut grips, military finish wear, and very light bore frosting with rifling present.
