The photo linked in post 34 does not have a bore evacuator on the main gun - the one in the article does. Also, the one in the article has the turret hatch on a swivel - this was never done on a BMP-1.
One of these things is not like the other...
It is not a PT-76. Wrong hull type. BMP hull.
And the Iraqis have been salvaging/rebuilding BMP1s and T72s. So they probably modified it in refit...
