Nice pick up Lummox.
I have reference to 13 variations too, in the pocket size tins, but some of the differences are really insignificant, one of them is just London without Manchester for instance, or differences in the shading on the table cloth or shape of the cork. I've seen 9 obvious variations. I'm pretty sure that rustytins has seen a lot more of these than I have though.
Actually I have reference to a 14th, pic below. The addition of a yellow box with M/M to what I take to be the earliest. Go figure.
I own a ten cig version of the early one, it is smaller as well as thinner and it has almost square corners.
Just realised that none of my reference have the same plant type as your large one.
Oh god I'm rambling
