What brand are these crossing signals?

[emdmike]

Maybe Z stuff for trains?  They do some G scale signals and I think they did crossing lights at one time.   Or possbily South Bend Signals as they also did some G scale stuff years ago.  

[Model Trains and Railfanning]

I was recently offered these g scale crossing signals for free if i wanted them. Anyone know what brand they are?
