Developed by BSA and Captain H.C. Boys under the name "Stanchion" and renamed on acceptance in 1937, the Boys Rifle fired a proprietary 55 caliber armor piercing round. While its original purpose, tank hunting, became unviable with advancements in armor, the Boys took up what is today called the "anti-material" role, smashing up lighter vehicles, insufficiently armored emplacements, and other valuable targets. Many were converted to 50 BMG after World War II, with few left in the original 55 Boys and fewer still brought back to the States. This particular example bears a "SA" cartouche on the left side of the frame, the acceptance proof of the Army of Finland. Though technically aligned with Nazi Germany and the Axis, Finland received material support from some Allied nations during the Winter War with the Soviet Union, including a number of Boys to supplement their native Lahti rifle. The rifle is fitted with the early "circular" muzzle brake left-offset blade front and two-position elevation adjustable peep sights and a top loading Bren-style magazine. The barreled receiver is installed in a steel frame with integral shock absorber, folding "T" shaped monopod, hardwood cheek rest and rear pistol grip, and a rubberized canvas shoulder pad with integral oiler. Included with the rifle is a custom-made transport case, a "SA" stamped metal magazine case, seven extra magazines, and a Leupold/Stevens Ultra M1A 16x scope with box (note: no mounting hardware included).

Fine with 75% of the blue finish showing some light scratches on the receiver and mild handling marks overall. The pistol grip and buttplate assembly are finished in green paint with bright areas along the high edges, and some light wear is present on the grip and cheekpiece. An unknown party has marked a bolt component "remove first, assemble last". Mechanically excellent. NOTE: This item is registered with the Bureau of Alcohol, Tobacco.
