1937 1938 1939 ? Chevrolet Nos Lower Cowl Vent Lever Knob Bakelite

Description

These are either a early Nos GM or early reproduction ? I have no part# or box.
Someone wrote 1937-1939 Chevy on the box with a question mark although I cannot
confirm exact application not knowing what color or design the cowl vent lever knobs were back then.
Any help in identifying these is appreciated?  1 3/8 inches Outer Diameter
I will guarantee them to work on those years of chevrolet cars but they may or may not be the correct
Bakelite Color? Buyer needs to confirm color of his original knob if thats what hes after.
All 12 of these have a slightly different woodgrain like pattern in plastic so dont expect it to be identical to one pictured
Or I can take a picture of the one you will recieve if your buying one.ALL ARE THE SAME COLOR
They also may have minor shelf wear.
