Here are all of the pictures.

I didn't include the pictures on my first post. this is my first M1. my grandfather was a shooting instructor at a place called Camp Dodge in Iowa. He was an expert on the M1 and also instructed on the 30 and 50 caliber machine guns. he traded MOS and was a Tank Commander in the 3rd Army WW2. what can you tell me about this from the pictures? what do I have?
