Eddystone Barrel Date Question

[fjruple]

I would like to note that a video does exists of a worker assembling the Model of 1917, placing the barrel into the receiver. He placing the barrel on the receiver as fast and efficiently as possible no attention is given to the markings on the barrel or the serial number on the receiver. These rifles were assembled with no thought of doing them in sequence. First in and First out. They were shipped out the same way.
