Apologies to cabezaverde. I got the article and have read it thru at least twice. Being a newby to Garands, it is taking awhile to digest everything. Meanwhile I ran across a reference to a book I had not heard of before. "The Essential M1 Garand" by Jim Thompson. I ordered it and it was delivered yesterday. Quite a lot for me to take in, so I'm going slowly. The only experience I had with Garands was in college in ROTC. Anybody remember when that was compulsory? Anyway this was in 1961/1962 and although having to work off demerits by end of school year cleaning of the M1's, I don't remember much of practical use.
But I do thank you for sending the article. It is going into my M1 file.
