This is a very scarce example of a WWII era US M1 Carbine manufactured by the Inland Division of General Motors that has been cutaway on the right side as a training/demonstrator model. The front and rear bridges of the receiver have both been cut away with the front section marked "U.S. CA/CAL." and the rear section marked "INLA/XA". The barrel still retains its full markings of "INLAND DIV/GENERAL MOTORS/4-43". The entire right side of the carbine has been nicely cutaway to expose all the inner workings of the carbine. Additionally, it has been cutaway through the chamber area, the top rear section of the receiver the side of the operating rod and barrel/gas block and gas piston area. This carbine will show all the inner workings of the model as if in an armorer training school. The stock and handguard are both early Inland manufacture that has the "IO" markings but no cartouches or proofs.
