The one on the left looks to be in excellent condition and the center one looks very good. The one on the right is rather rough but for what you paid, I'm sure you're not complaining. Having at least one of the control buttons is icing on the cake.
I have two buttons the on the right the billboard is in good shape. So cleaned it put new wires. General cleaning the other two were a mess rusted bad shape. The middle billboard couldnt save tryed but couldn't. So rewired both cleabed and repainted. Both light green ones have the lights. Also thankyou.
