I have opportunity to buy 30 Cal M-1 Garand Springfield Armory for $1,000 serial 816,805? Anyone know anything about this gun? Comes with lots of ammo. Markings on the side lever is 'NM' . Other front markings is 'D28287-12SA, S-06 with a Diamond following the 6. Any information would be appreciated. It looks brand new never fired. My friend of a friend is selling it because an old man died. Please help. I can send many pictures.
