Troy,
It was almost 20 years ago that I ran across a few of these at an electrical contractors shop, If I remember correctly the flashers did look like yours, but I am not sure if the flasher was made by CH. But looking at your picture the gears, shafts, disk, bearing mounts, and frame look simular to the ones used on the CH TSS-18 flasher. I would say there is a very good chance the flasher is CH. Mabe someone in the group has a CH airport lighting catalog in there collection and can see if they show a picture.
