There was a variation for the Vintage Collection Luke Skywalker VC23 figure. The first version didn't have a hole in the belt so the lightsaber couldn't be plugged in (the lightsaber hilt also didn't have a peg), the second and corrected version did.
VC23 Luke Skywalker variation, pictured on the left is the first version with no hole in the belt and no peg on the lightsaber hilt.
