I am currently cleaning the reciever of its gunk so I can see the markings, but some genius decided to epoxy the rear sights to the top wood and the top wood to the barrel, so I can't get to the markings around the throat of the barrel. Who does this?

Also I am new to markings on these rifles, so I do not know what SA markings look like, but I'll clean it up and get some more pictures soon enough.
