The US Enfield by Skennerton has the story of the transition from P14 to M17. IIRC all the spares and tooling were sold by the British for about $900,000; it had cost them over $20,000,000. in gold.
The assembly record for the P14 was about 50 rifles a day per man. For the M17 it inexplicably jumped to 280 rifles a day per man!
The P14 cost on average $42. each. Each M17 costed out at $26.00 each
This is how the USA ended WWI as the world's largest creditor!

The three plants also turned out non-compatible guns/parts, yet the p1917 didnt have that issue?
