Has anyone seen a picture of contestants in 1968 wearing a National Trouble Shooter Finalist Jacket back in the day?

They seemed to have variations on the style/materials from year to year. Some years there are a lot of pictures on the web. Other years none seem to pop up.

I have included a few pictures from my collection.

The first jacket that I show on the left is from 1966.

The there are pictures of this on the web from back in the day.

I have never seen a dated picture from 1967.

The 1968 is what I am asking about.

Tons of pictures of 1969 on the web. Snap closure white buttons on it with the new collar. 1970 went to the zipper closure and the new collar.

Second from right is I think a 1976. 1975 had the State patch above the Nat. Finalist patch. 1974 was a "Wet" look jacket. So I am guessing 1976. Does anyone know for sure?

Then the one on the right is 1980 or before. 1981 had AAA as a partial sponsor and there is no AAA on the patch of the jacket I show. Does anyone know the year on this one too? Thank you.
