50mm summilux asph 1.4 black and chrome weight?

[qruyk12]

why is it everwhere I look the black and chrome 50mm asph 1.4 lenses come back at the same weight of 335g

I thought chrome weighed more? I am thinking about getting one of these and this puzzles me.

It's a mistake in the listing, originally by Leica. The chrome one does weigh more, 130gm according to this link.
