testing out a leitz wetzlar 250mm projector lens on the speed graphic. I thought it was ~f2.5 but it looks more like f4 - the negatives came out underexposed and I had to push them a lot during scanning.
I don't have photos of this specific setup, but here is its alternative setup, my old Anniversary Speed Graphic with the Leitz Wetzlar Hektor 150mm/f2.5 lens:
I sold the Anniversary a year ago because I got a Pacemaker, but I kept the lens. It's mounted on a wooden lensboard, which I trimmed to make it fit to the smaller Pacemaker lensboard.
The 250mm/f4 (I still haven't been able to find out its official name, I think it's a "Diaron") is pretty much the same beast like the Hektor, only you have to fully extend the bellows to get a close-up portrait.
I need to buy myself a Speed at some point, so versatile and I love plonking any old bit of glass in front of film to see what happens. Well done and thanks for the inspiration.
