A note on your M1 Carbine. I'm not sure what state of originality it's in, but one that has matching parts, and a stock with appropriate markings, it can be worth a tidy sum. The picture shows that it doesn't have a bayonet lug.
Only the last batch of carbines produced during the war had bayonet lugs. But at the end of the war all the carbines were sent back to the armories to be repaired and updated for redistribution, such as to CMP. Among the updates were new bayonet lug front bands. These guns have a much lower collector value because they are not original.
The lack of a bayonet lug suggests the possibility that your rifle was liberated during the war and bypassed the armory restoration (or someone may have simply replaced the front band with an older one). The odds are slim that it's all original since they are very rare, but it's worth checking out. If the components match it may be a nice collector's piece. The picture indicates that it's condition is good... worth keeping, IMO.
