I have seen old black-wrinkled equipment that had been left in a humid
environment for a long time. The wrinkled finish had blistered and peeled,
but beneath the wrinkle coat there was an unwrinlked black coat still
intact. I don't recall if that sub-layer was gloss or flat, but apparently
it was used as a primer under the wrinkle coad.
Maybe that's why the wrinlke coat blistered and peeled.
I have noticed that the wrinkle finish on1930's era pre WW2 gear has a
texture that is very different from post WW2 wrinkle finishes. I have
looked in vain for any information on how that 1930's finish was attained or
how to duplicate it. The old-style wrinkle has a grainy texture, while the
more recent wrinkle finishes are very uniform, whether the wrinkles are
coarse or fine.
