This one is for you Dyar. Besides I couldn't be bothered looking for the post where you were talking about how different molds should, in theory, make different variations.
I guess the nurses I posted earlier were a good example as they were all made in Hong Kong and the only difference was the mold #. They were similar looking though.
These 2 footballers however are a different case altogether. There are distinct differences between the two with the only difference in the markings being the mold #. Both have W. Berrie Co on their arms. The one on the left has a #3 mold number and the one on the right has a #1. The one on the right seems to have his nose pointing up higher as if hes looking up more rather than straight ahead.
