Here is my run of what I believe to be all early versions of the ever popular Star in Shield Cutter.
The first is the earliest "Barrel Top" , and next to it is the "Pointed A" which I believe is the second variant. Third is the "Flat Topped A" and finally the "Curved R" " X Base" type. Sorry for the technical terms...I am not totally up on my Thomas numbers...
Am I missing any in the family tree?
