I bought this M1 shell for $20 a few years ago because nobody can pass up a M1, right? I pulled it out of my closet and I'm trying to figure out what I can about it. It has a front seam and I believe cork coating? The only stamping on it is "101G" It has later model swivel bale and a single snap chin strap.. It's driving me crazy trying to figure this out.. I'm going to try and find a liner for this shell once I figure out more about it.
