As Issued Model of 1917

So were they originally parkerized then or refinished before they left the factory? I have an 11-18 dated barrel that is parkerized except where the front sight base was. In that spot it is blued.

The barrel I mentioned is an eddystone.

According to a recent history of the Eddystone plant:
"The browning procedure was replaced by a process developed by the Parker Rust Proof Company. This new process came into full operation at Eddystone by September 1918, resulting in a decrease in manpower from 305 (for the browning process) to only 80 (for the Parkerizing process). "

I have another complete original Eddystone from just a month or two before the one in the OP. It has the earlier blued finish.

For comparison.
