I can't say for sure, but because of the triple extension bed, the shape of the bracket connecting the rear standard to the bed and the knurled knob on the front standard, my best guess would be a Zeiss Ikon Universal Juwel. It could be an earlier or later model, or maybe something else altogether. Many of the German folders of that period look remarkably similar.
One example.

I believe it probably is a 1930's-40's Speed Graphic since that's part of a photo of Dorothea Lange from that era. The full photo has her on the top of a car, and you can see it among the photos in Mary Street Alinder's Ansel Adams: A Biography. I just finished re-reading the book today.
looks like a folder .. the front standard framer / composition tool is a dead give away ...
It can't be a Speed Graphic in the posted image. The shape of the front standard, the brilliant finder, the disconnected front bed, the shape of the main box -- all those details are completely different on a Speed Graphic (any Speed Graphic). The camera looks like a European 9x12 plate camera. It's difficult to be certain about the exact make and model.
Here is a slightly higher resolution version of the image found with a google image search:

Zeiss Juwel seems to be the closest match.

Book reference: "Daring to Look: Dorothea Lange's Photographs and Reports from the Field" By Anne Whiston Spirn
Page 323 confirms that it is a Zeiss Juwel which produced 3.25 x 4.25 inch negatives.
Just to add to this old thread, I have a ICA/Zeiss Universal Palmos 9x12 that has the same rear balancing extension feature
