This 22 caliber Frontier Six Shooter instruction manual measures 3-7/8" x 9-1/4" closed and opens to 15-1/2" x 9-1/4" with 8 pages/panels.It has an exploded view,parts list and complete instructions.There is no date or code but I believe it to be Circa-1960's.This and the Colt Frontier Scout manual of the same time are as close to identical as possible with the brand difference. Very Good+ condition with some bump creases and fold creases thinning
