I just snagged this blower that im guessing was used to move contaminated air out of a fallout shelter.  Seems like it will move some big air and may be a bit big for my little brake drum coal forge. Was wondering if anyone could provide some info on it. 

Did you get it Out of a fallout shelter?

yup looks a bit big for a brake drum forge. Dosnt mean it couldn't be used for one if you wanted to. 

Yes the basement of my fire station was a fallout shelter and that's were I got it from. 

Ok. That's pretty interesting. So is it Both hand crank and motor powered?  How much air does it push when lightly hand cranked? 

Sorry I don't have any info on it. Just curious. 

Yes but I havnt plugged the motor in yet to see if it works. The hand crank seems to move air pretty well though. I think I'll just fab up a damper to restrict some air flow and try it on my forge. Better than a hair dryer I guess

Check the gears; some of the CD blowers were engineered for fairly low usage; I don't recall if Buffalo was one of them.  I'd can the electric option unless you are running a very large forge for large items.  I much prefer the control of a hand cranked blower!
