On a recent Thanksgiving trip to Houston I stopped by to get some pictures of my old Thunderbolt blower at a friend's house.
I looked up the name Sutorbilt and found this website. Apparently they are still in business making roots blowers. http://www.gardnerdenverproducts.com/blowers/sutorbilt/
Here is what the motor ID tag says.
Temp.Rise: 40 Degrees Celsius
H.P: 7 1/2
Serial Number: 208074
Federal Enterprises, INC.
Chicago 19 Illinois, U.S.A.
Formerly Federal Electric Company, INC.
Here is what the siren ID tag says.
Manufactured by Federal Enterprises, INC
Chicago Illinois, USA
Serial Number: T-447
Formerly Federal Electric Company
The ID tag that was on the rotator box of my siren was sandblasted and now is unreadable. Could somone tell me how old this siren is using the serial number off of the ID tag that was on the blower frame?
