DRGW Krauss-Maffei Fan Size

the title says it all just looking to see if any one on here knows the fan size or can dirrect me in the right direction. tired of looking on web and not finding what I'm looking for.

 

You should be able to extrapolate the size from the drawings here:

ML 4000 C´C´ Prototype for the Denver Rio Grande Western Railroad

Thanks its much more than I needed and actually is going to help me with the rest of my project.

 

I can also see if the manual has anything, since I have
an original locomotive operator manual for the DRGW units!

 

From what I thought I found, and currently can't find, the units have:

2 x 36"
1 x 48"

Still looking through manual. Will update once I'm certain!
