Thought this was interesting:

We have talked in the past about Penta wheels, and how there is differences between the different makers, AMG, AST, Ronal etc.. etc..
I think young Oscar did some picture investigation on this, well this picture is quite good, shows a side by side shot of different wheels, and you can see how the spokes, or arms of the wheels are indeed different.
So not all Penta wheels are the same.
