Later made GM over the counter,(not used on the assembly line during 69/70),cowl ind. air cleaners,(w/o thermac),came with a vent tube that now had two 45° crimps in it,but still showed heavily defined wrinkling.
The Taiwan reproduction market and eventually stamped C H Q,copied that later design but ignored the wrinkling altogether.
It's a very nice part,but I agree,this looks like one of those,as the real ones used on the assembly line during 69/70 had the one 90° bent vent tube with heavy wrinkles,along with a noticeable notch cut out in the center of the snorkle seam.
Two 45° crimps shown below.
