Does this mean that 26,000 rifles were detail examined and one-half found cracked? If so, who did the examination? it would have to be a major facility and that many rifles with cracks would have been a discovery of monumental importance. I would suggest it is more likely that a spot check of a sample found some cracked receivers, perhaps all in ERA rifles and that led to the ERA rifles being returned. The later memos show a frequency of cracking much lower than that implied in the comment about the 26,000 rifles. But the frequency in the detailed exams is still troubling although lacking in specifics about the individual rifles (like were they re-barreled).
Source document studies are very important but not all info was recorded and much has been lost. A useful adjunct to this would be a forum survey asking owners of M1917's who have examined rifles in detail to mention instances of cracked receivers with details of manufacturer and whether or not the gun has definitely been re-barreled. Conclusions drawn from old documents still have to be vetted against reality. This thread (and the one on Gunboards) is leaning in the direction that original Eddystone M1917's are prone to receiver cracks whereas numerous threads from the past (based on exam of rifles) would appear to me to contradict this. The whole issue is of importance to owners of ERA rifles as a blanket determination of susceptibility to cracks might affect their value.
