Idk about government agencies, but contacting the company does work.
There was a crane in Brainiac that we couldnt identify. I contacted the company "Lee Lifting" (there site even says that they have appeared on that show) and i got a reply back with the make and model.
It's a Kato NK500-EV. So if someone could please change that.
