I can't recommend this often enough. https://thegca.org/# They are ate up with Garand trivia. I borrow my sons copies as they come in. So I can't nail down the particular issue about the barn stock story and eventual inventory. But if I recall they did about 2 or 3 stories on them. It was a big deal when this urban tale turned out to be true. I usually read the "Journal" cover to cover. Multiple times. Only own one Garand now and try to exercise it around June 6th. It's a 6 digit made in early 1941. Not a beauty queen, but it will do.
