The accompanying factory letter lists this revolver as originally shipped with a 4 3/4 inch barrel in .38/40 caliber, blue finish, grips not listed when shipped on June 10, 1903 to Carl Engel of Butte, Montana, c/o Winchester Repeating Arms Co. New Haven Connecticut. This was a single gun shipment from Colt, likely combined in the same shipment as a Winchester gun due to having a geographic location nearby in Connecticut. Carl Engel (1871-1956) owned a successful sporting goods store in the lively mining town Butte, Montana that sponsored lots of local shooting events with the Butte Rod and Gun Club. He was also a member of the Scottish Rite Masons, later a deputy sheriff circa 1925-1931 during Prohibition, became an insurance agent after 1931 and resided in Reno, Nevada circa 1952 until his death in 1956. Upgraded with a factory replacement 5 1/2 inch .45 caliber barrel with the one-line Hartford address on top and "COLT SINGLE ACTION ARMY 45" on the left side. The left side of the frame has the two-line, three patent dates marking followed by a circled Rampant Colt. Matching serial numbers are on the frame, trigger guard, and back strap. Replacement .45 Colt cylinder. Assembly number "5394" on the loading gate. Checkered hard rubber grip panels both hand-numbered underneath "9406B", with the right side grip having a crossed out "6860". Provenance: The John Fox Collection
