Folks,

It isn't a 'dorff. I have one, and the Deardorff rear standard braces are not curved beyond the bottom of the brace. The Deardorff rear standard brace is straight along the adjustment slots, the one in the commercial is curved along the adjustment slots.

There is another candidate besides the Wista though, the Tachihara. There's a thumbnail here:
