New addition to sign collection needing repair

Recently picked up this scrolling sign at an auction. Unfortunately it does not scroll right now as the motor is gone and I really want to get it working again. I was hoping someone out there might have a unit like this that could help me find a motor for it. Even if your sign does not work but still has the motor that would be fine, just need to find the correct style of motor. Many old signs of this type used clock motors but there were/are many types of old clock motors. Any photos of your old motor would be greatly appreciated! Cheers, Nick
