To verify for everyone the notch was not done at the factory, hence why it's called a field notch, it was done in the field and not at the factory. This is also why it doesn't have a c stamped on the side. Please read the description before putting up the obvious. Have a great day. Thank you for all the help that has been private messaged to me, we very much appreciate it. The more we learn about these guns the more we learn about history (invaluable). We will consider all the offers we received and will make a decision soon in the new year as to whom it will be sold to (full price has yet to be offered). Have a great new year everyone and continue sending info via PM, as we can always learn more.
