60b - Site Hut truck - unlisted variation

[tandyfan]

In NJ's list the darker blue variants always had centre rivet. Mine does not.

I look at all the rivets and blue shades of all the Site Trucks I come across and have yet to find that one. I think it must be quite hard to find, but it is subtle so may often go unnoticed. Nice find.
