I am filled with shock, I didn't know there was this one!, Though what happened to the other intake?

Lol they added some horns that face upward. Pretty interesting find!

Richardson, TX has a 2001-DC that was replaced by a T-128 LINK:https://www.google.com/maps/@32.9851078,-96.6651287,3a,75y,15.72h,93.49t/data=!3m7!1e1!3m5!1sLpvgQ0CzRmXEqrEboXuZGA!2e0!5s20120701T000000!7i13312!8i6656 EDIT: there is another one: https://www.google.com/maps/@32.9969139,-96.6234218,3a,4...

You forgot the one in Davis - Besse NPP in Oak Harbor, OH.

Oh Thanks for that info

This might be off topic but I found the ACA Website and it shows the T-121, The P-50, And what seems to be an early T-128.
