I recently picked up a real clean model six 30-06 at a gun show, the gun shop selling it didn’t know much about saying as he was loading his truck to go the show a guy pulled in wanted to sell six guns so he bought them and through them in the truck. Anyway it appears to have been shot very little , it has a 18.5 inch barrel and everything I have seen said they only came in 22” barrels? Has anyone ever seen one in 18.5 from the factory? The rifle also has a recoil pad that looks factory but most I can find pictures of have a butt plate. Could the gun have been ordered like this or do you think someone had it shortened and added the recoil pad ?
