This submachine gun was an
Australian-designed private venture. The blueprints were sent over from
Australia to Birmingham Small Arms in Britain and BSA created the
prototypes. It was side-fed from the right side. The pistol grip was a
folding metal tube and a spare magazine could be fixed to the rear end
of the weapon to form a rudimentary shoulder stock. The two return
springs were mounted on rods that were visible above and below the
barrel and they passed through the bolt. In 1943, Ordnance Board conducted
a trial at Pendine from the 22nd of September to the 5th of October. The
BSA-Andrews was among the weapons being trialed. Users complained of the
flimsy stock and the overly thick body. No further action was taken.
