Navy Garands

[Bob Seijas]

From the 2012 article:
"Of particular significance is the fact that none of these receivers
had a barrel with 7.62 MM marking. The implication is that the
initial intention was to mark only the receivers, not the barrel.
Although that would allow the user to see the right cartridge for
the rifle at a glance, it consigned that receiver to only that cartridge
forever. If another caliber arose in the future or if it became
necessary to put the rifle back to .30-06 for some reason, simply
putting on a different barrel would not suffice. Besides, it wasn’t
the receiver that was 7.62, it was the barrel. This was evidently
realized after only a small number of conversions (reportedly the
first 100), and marking the receiver was discontinued."
