Same as the other one.

No two British DRs are exactly alike and distinguishing what is original from what is not isn't always easy. Shortly after I got my current .400 a British gunmaker, Kirk Merrington, said the rear express sight base was a replacement. I had wondered about that because it looked like it might be to me, so I presumed he was right. I now have four friends who have the same rifle, in the same caliber, from the same trade maker. The rear sight bases on all five rifles are the same. Two have a folding tangent sight behind the folding leaves and one has four folding leaves instead of two, but the bases are identical. Kirk apprenticed with Churchill's and knows British doubles, but he was wrong.
