Colt Long Flute Series SAA Description
in 1913, Colt decided to make use of approximately 1500 cylinders left over from the model 1878 double action production. Since it was necessary to add a bolt lock notch and a lead-in groove on these long flute cylinders, a block of serial numbers, 330,000 to 331,480, was set aside to be used for this special production. Manufactured in 1913 and 1914, specimens are known in .32 WCF, .38 WCF, .41 LC, .44 S&W Spl., .44 WCF, and .45 LC cals.
According to researchers Hull and Rowcliffe, whose survey includes 114 long flute Single Actions, few .44 WCF have been noted. The actual total mfg. may possibly exceed 1,500, and while quite rare, these long flute variations sell for only 5% to 10% more than other Single Actions of this period.
