Shinra Remains

During the visual introduction to Edge, the city that has risen in Midgar's remains,
we can see the remains of the gigantic cannon used to destroy one of the Weapon
monsters in the PSX Final Fantasy VII.

Just before the full cannon is revealed onscreen, you can see
a faded Shinra logo on a piece of shorn scrap metal.

The Shinra logo appears framed
on the wall of Rufus's room at the Healin Lodge

Reno's rod also bears the Shinra logo.
Apparently the Turks used company stock for their work.
