Re: Colt 45 serial # 53872
Hi Boxter.....welcome to TFF. Is that Boxter as in Porsche Boxter?
Anyway, according to my list, your SAA was made in 1880. If any of those patent dates are later than that, something's wrong.
The "3872" on the cylinder simply indicates that the cylinder matches the frame.
An 1880 manufacture date would make your revolver a Civilian "Intermediate Black Powder SAA (Ser. # range 22,000-130,000) or a Military "Mid-Range U.S. Model SAA" (Ser. # range 30,693-121,147) and it's potentially quite valuable (depending on condition). Also, does it have any military markings, like a "U.S" stamped on the handle or frame , or a three letter code stamped on the frame?
Please post several good sharp, clear photos of the revolver, if you can.
Also, please post ALL of the writing on the gun, EXACTLY as, and where, it's written.
