could be an optical illusion but it almost looks like the generator/ compressor thingy might not even be connected to the horn. its hard to make out due to the fact that its dark and grainy but could it be possible that the thing bolted to the center of it a bracket or chain guard that is running parallel to the face of the generator fore of the unit and the horn is not connected at all to it? just a possibility to be considered. i may be seeing things wrong but it looks like that to my untrained eye.
