Photo plates. That's the only thing I can think of (its early, I've had no sleep, etc) that could really do it manually. Maybe with some kind of parallax? I'm really not up to speed on this but maybe a forward and backward looking photoplate then look at red/blue shift. Not sure what the speed scale would look like for something like this.

Would that work?
