This is an interesting news report.

However, I think the attached sentence is quite an exaggeration.

IMHO - The changes to the British Lee-Metford and Lee-Enfield arms in the period 1892 to 1904, were even more extensive, with even less interchangeability of parts, between models.

The Krag-Jorgensen design remained recognizable throughout U. S. production and a lot of later parts will work on early models.
