Potential win-13 garand purchase question?

[HOOKED ON HISTORY]

I have the opportunity to acquire what appears to be a very nice WIN-13. Very nice overall with minimal throat & muzzle wear and nice cartouche. At first glance all the internals look correct. My only concern is the front sight. At its widest point it measures .761.
I thought the Winchesters were closer to .800 and had a punch mark of which this one has no such mark.
Any fellow GCA members / experts about to verify or deny.
