To the other two Davids, I think there's a little confusion here. On the truck serial numbers there's a 200 spread, not 2000. That makes quite a difference. From the 7th to 11th there's five working days. That's 40 units per day. Those Nov 11th trucks have a 38 unit spread so what's the problem? It's definitely a rare coincidence to come across the three that were built on the same day especially when you consider that they're the only F8s I've come across. When you think about it, though, they would have all been demobed out of the same base (Edmonton or Wainwright?) and when they received maybe 20 or so units at a time from the factory the serial numbers were likely close together and could have been all in one day's production.
This image was painted on the hood of 21634. It's a terrible pic that I had to doctor so it'd be legible because of a dark shadow across it. It's a fairy holding what looks like a rod with something wrapped around it. It looks like it was military. I'll try to get a better picture.
