Anodized Campy NR crank?

I picked up a Raleigh Professional frame the other day, and pulled the cranks. They're standard issue Campy NR 170s...except when I put them next to each other, I notice that the NDS is the standard silver color, but the DS is more like a Ti-finish/very pale gold anodized color. Now, I know that Campy made a gold ano BMX/track crank, but all the pics of those on ebay show a much more pronounced gold color. Here are mine...can anyone tell me what's up with these?

Weird, Never seen that. They appear to be a match, same date code and everything. Could it be some sort of UV exposure yellowing or something?

What do you want for weyless (or whatever they are) type skewers? haha

Anodizing can fade over time. I suspect that is what happened here.

That's what i thought too, but it's so uniform in color...even areas that would be covered from the sun are the same color.

Last time I this was when one guy swore that LPS3 was THE chain lube. I think they just picked up colorant from something of that sort, yes pretty uniform. Clean/soak it with MEK or lacquer thinner for a while.

My first thought is perhaps the cranks were on a display bike in a shop window for a long time and only one crank got regular sun exposure.

They're just dirty and stained from oil/grease.
