Here is a very desirable U.S. M1 30 caliber carbine manufactured by Rock-Ola. This carbine has serial #1694497 on the receiver, a "Rock-Ola" marked barrel with a bright bore, a two rivet handguard and a high wood pistol grip stock with proper early wheel acceptance mark and "RMC" inspection marking on the right side as well as a small stamped "RMC" on the left side within the sling cut. This carbine has the type B safety, unmarked early style type C operating slide, type B magazine release stamped "A-R", type A front band, type C recoil plate stamped "Rock-Ola", type A trigger housing stamped "Rock-Ola", a "KR" stamped type C hammer and a type A non-adjustable for windage rear sight stamped "S" on the left side and "RR" on the right side. The metal surfaces retain most of their military dark drab greenish finish with honest wear in the usual places such as the right side of the receiver where the operating slide makes contact and on the breech bolt. The butt plates finish appears to have more of a grayish color to it. This carbine includes a sling, oiler and an "R-O" stamped fifteen round magazine which retains a regular blue finish. A great example of an early Rock-Ola M1 Carbine.  {C&R}
