This is a 1944 Maltby produced No4 Mk1 Rifle that was cut down somewhere along the line into a carbine configuration. Light and handy, it is very accurate at 100 yards. Recoil was not bad, but the blast and flash signature is excessive.
Overall a really nice carbine that makes a fine companion on the Northern MN woods.
Caliber: .303 British.
My friend Darrell shooting the carbine...excessive muzzle signature.
