This is a nice example of an early Rock-Ola M1 carbine. The rear of the receiver is marked "ROCK-OLA" over the serial number and the top of the barrel is marked "ROCK-OLA", "5-43" and "P". The carbine has a blade front sight, early variation flip up rear peep sight, marked "S" on the left side and "BR" on the right, unmarked magazine release, dog leg "KR" hammer, blue flat top bolt and mounted on the First Variation high wood walnut stock with wide groove hand guard, "I" oiler slot and checkered steel buttplate. Additional Rock-Ola markings are present on the trigger guard, operating rod, bolt, trigger and sear. The right side of the buttstock is stamped with a boxed "RMC" and cross cannon cartouche and the sling slot is stamped "RMC". Complete with a green canvas sling. An exceptional early production Rock-Ola M1 carbine!
