Thanks, DWFII. I have seen the high gorge, notched lapel waistcoats, but I was thinking of something a little different.

There's no notched lapel on the waistcoat, and it has a high wide "V" shape; about as high as some of the pull over sweater vests. I would guess that there are a few more buttons, too. The two sides of the waistcoat closure would probably cross between the second and third button of a shirt. And now that I think about it, the pictures I'm remembering probably were from the early nineteen-hundreds.
