Before radios, the ATSF used wig wags mounted on their way cars in order to communicate with the crew on the head end. This is a limited run and I only have a few dozen pairs left.
Get yours quick before they are gone. Who's knows if we will ever see an O Scale ATSF Wig Wag when these are gone.
These ship FREE if purchased separately. If you are charged for shipping, I will refund it when I process your order.
