The picture that is on Retract's web site does not do them justice.
Remember the mirrors in the 1st three pictures in the photo album are 36 years old.
The 4th picture (fuzzy one) is when they were fairly new.(1979)
That is when they still made the tubes out of stainless steel.
I called them to see if they would do a special SS order.
They said no because they stopped being a job shop 5 years ago.
So you will have to use the coated white tubes or have them chromed.
I have to say, they held-up pretty well after 36 years.
