Series B, Mk. II with low No.279 serial number. 47 inches in length. Not an actual firearm but rather used as a training device for novice recruits. Developed to instill the basics of good marksmanship without expending scarce ammunition or depriving the frontlines of functioning rifles. Instead of firing projectiles, the Swift rifle used a spring-loaded pin that punched a hole in a target fixed one inch in front of the “muzzle.” The location and shape of the hole punch would indicate if the shooter was using proper aim and form. According to the rifle’s training manual, “This teaches the trainee to keep motionless at the moment of the release of the trigger and for the fraction of a second after, because, if he moves, or jerks the rifle, before the pins have sprung back out of the paper, the edges of the holes will be torn; and if he breathes while firing, the hole made by the pin will be oval instead of completely round.” To familiarize the trainee with operating the action the rifle was also equipped with a moving mock bolt that had to be fully cycled to engage the trigger. To teach recruits to hold the rifle firmly against the shoulder when firing, a depressible butt plate had to be fully engaged against the shooter to pull the trigger. Expected age wear and prongs broken short. A piece of 20th century ingenuity necessitated by the circumstances of total war.
