I am positve it said "Maj" abreviated, and the lead to the gun I posted from the museum also said major quantrill.
Its funny, because somehow I still remember as a kid at first thinking it said MAY Quantrill. I remember wondering at the time if I had discovered a illicit romance but on closer inspection saw it was "Maj" quantrill. I was about 16 years old in 1957 or so and still remember my 1st look thinking that! Amazeing huh? I cant remember in detail everything I did yesterday! I am very sorry to see that the holster burned up. That inscription was burned right into the inside flap of the holster by a iron or something. I remember it like yesterday.
