Hi Scott,
Remember that these are only small things that could be remedied,
Brass finish on height adjuster (should be green) but I like it as is.
Fasteners are Nickel plated (should be bright dipped zinc)
Thrust pad is brass finish (should be green) again I like it.
Pinch Weld on chain case (simply remove it)
As far as the overall colour is concerned are you saying it should be a tad darker ?
and,
I have to ask the question, why is it up for sale ?
Cheers,
BB.
