While it is true that the Army scraped (and Bannerman bought and rebuilt) low # 03s, the Marine Corps did not. As an "oh by the way" quite a number of low # 03s were on Guadalcanal. The records of failures in that time period were compiled and the low # ones were close to twice as likely to fail as the high number ones....but neither approached the odds of being struck by lightening (and although you wouldn't think it by the way folks talk, the high # ones had a failure rate as well.....as do virtually all heavily used military weapons). Since Army scraped them and the Marine Corps (and most of Navy) didn't, a WWII issued to US military low # rifle was 95% certain to have been Marine Corps. Many of these were reworked when turned in by the Marine Corps and became part of the anti-communist military aid shipments to Greece. So the low number ones that were returned from Greece not too long ago were likely MC rifles as well.
