Hard to tell if it was heavily buffed or just 'dipped', but does look reblued.
When I look at a blue job, I concentrate on the edges as shown in pics below. If they are sharp and not rounded, I view it as an
A+ job; IOW, a 'dip'; not a buffed to hell & gone job...
Unlike others here, a 'dip' reblue does not diminish the value to me...Buffing the snot out of it does...
