I got two SNES controllers today and between those and the two I previously own, there seem to be three different variations.

The first one has the SNES logo on the front. The L and R buttons have the letters in a dark gray color. It is part SNS-005

The second one is the same as the first one, however the L and R buttons are not painted dark gray.

The third one has a Nintendo logo on the front (instead of the SNES logo). The back shows the Super Famicom logo and is part SNS-102. It has purple buttons and is in a light gray case.

All of the controllers are 1st party. Does anybody know anything about these differences (sorry, I do not have a digital camera available to take pictures).
