This just a simple question.
Has anyone on this board every seen a Thompson (of any kind: 21, 28, M1, M1A1, WH28, etc.) actually wear out to the point that it could not be repaired to function reliably again?
I am not talking about cracked or broken receivers, but receivers actually worn to the point that a gunsmith would say "It's worn out. Buy another gun."

Some M1's went through years of hell in WW2 and are still being shot today!
