I have these, but mint mean different things to different people.
I parted out first gens in the 80s and saved all the good parts for me

But since I have verts, these appear to be coupes. The arms are about 1" longer than a vert. But I am not sure what they came off of.
The blade holders are about 1/2" longer than my 69 verts and have a more rounded profile than my peaked 69 arms. Are they 68s?
no gouges on the arms, clean of bubbles except for one downward side of an arm (shown), but rest of them are clear.
blade holders are Trico, but no stamps on the arms that I can see. Not even sure these arms came with these holders, they have been separated for a long time.
