I have several Duotone Frontier Scouts and like them pretty well. Generally, the Q serial numbered Scouts are worth a little more than the F numbered guns, but the difference isn't much. $350 is an excellent price if the gun is in really nice condition with box and papers. The Q serial numbered Duotones were only manufactured for about five months (November 1957 to March 1958). Colt changed the letter suffix in the serial number from Q to F and continued production until sometime in 1960. About 40,000 Duotones were produced so they are not actually very scarce. However, ones in nice condition are getting much harder to find these days.
